Measure the string height at the bridge:

• if it is over 1/2 inch (13mm), then it is the G model.
• if it is under, then it usually is the F & T model.

The F and T model are identical EXCEPT that the T model has the plate of metal that wraps around the bridge pick up (like a standard Fender Telecaster bridge does).

EverTune technically does have floating saddles that do tremolo when moved with a finger or the EverTune hex key. However, it is designed to be a fixed bridge and the floating saddles are only necessary for constant tension.

We do plan to make a tremolo EverTune, however it is impossible to say when it will be released.

EverTune can be fitted into most guitars that have Floyd Rose and Kahler and any other tremolo bridges.

However, it is always the case that EverTune will require its own custom routing and in many cases some small wood holes from the previous bridge route will have to be filled. We have seen many guitars with Floyd Rose and other tremolo bridges switched to EverTune and any qualified local Luthier and tech should be able to perform the installation if she/he first looks at the info here.

For a list of 3rd party installers that we know of see here.

Coated versus Uncoated:

We recommend coated strings. This is because rust (oxidation) actually adds weight to the strings. The effect of this extra weight is seen over the first few days to one week as the pitch may drop slightly (5 – 15 cents) and very gradually. With coated strings this tension drop is usually avoided. Without coated strings it is easy enough to re-tune slightly every couple days until the rust coating covers the string.

Wound versus Unwound:

We recommend wound strings when possible. Especially in the range of sizes 016 – 026 (usually the G string). Wound strings are more flexible, and interact better with our constant tension saddles.

The saddle to saddle spacing is 0.41 inches (10.4mm) on average. The saddles are floating and as such do have some side to side mobility so the spacing can vary a tiny bit from this average but is usually right about on the average.

What’s the difference?

The only difference between G model standard and G model long is the length of the plate circled in the image below.

The G model standard is made to come right to the pickup bezel of the bridge pickup of a standard Gibson Les Paul. Sometimes, especially on Les Paul style guitars made in Asia, the bridge pickup is placed farther away from the bridge. In this case the long should be used so that the faceplate can stretch to the pickup and avoid any gap.

The diagram below shows the measurement for the standard bridge. To take this measurement, first, we have to find the ideal scale length point and then we have to measure from that point to the start of the bridge pick up bezel.

The below video (take only seconds 9-27) shows how to find the ideal scale length point. If the measurement from the scale length to the pickup bezel is 0.55 inches (14mm) or below as it shows in the diagram then this is a standard G model. If it is longer than please note on the order that it is a LONG G model.

Also note when ordering the long G model the installer will have to trim the front of the G model to fit the length to the pickup bezel. This means the installer will have to cleanly cut aluminum without flaking the plating.

In traditional telecaster bridge pickups, a large nub extends under the pickup on the bridge side of the pickup. Since the bottom of the EverTune bridge also extends under the bridge pickup, it is often necessary to flip the bridge pickup 180 degrees to install. This moves the position of the pole pieces slightly. In our experience, this slight move is unnoticeable tonally.

People interested installing themselves please refer to the FAQ that covers that: CAN I INSTALL THIS MYSELF

As of August 2017, we have started offering installations for customers that want to send their guitars to us through our INSTALLATION PROGRAM. Our price for an F & T model installation, stringing and setup is $300. Our G model price for the same service is $350. If you choose to have us install, please fill out our INSTALLATION PROGRAM form and include a front + back photo of your guitar. We will review and send a quote within 72 hours. Upon acceptance of our proforma quotation, send us the guitar for installation. Turnaround time is about 2 - 3 weeks.

When using an installer from our list please remember that they are third party. They do not work for us. In general their prices range from $150 - $350 for F model installations and $250 - $500 for G model but each installer is different. Also, when we compile this list, we only check if they understand the requirements for routing an EverTune and if they are capable of performing that route. We do not know how they perform at guitar repairs and modifications in general or how they will treat each special case guitar. The customer must communicate directly with the installer to ascertain this information.

To install an EverTune bridge a route pocket must be cut into the guitar. Anyone who is comfortable with wood working and has a router, CNC, or manual milling machine can make the appropriate modifications to his/her guitar.

When installing into guitars that had a tremolo, the tremolo pocket usually extends passed the EverTune bridge and will be visible as a hole unless the installer plugs it (preferably with wood from the back of the guitar that would be cut out during the installation).

In the case of routing the pocket manually, we do sell template sets that are complete with all the tools needed for the installation. We also have available files of the pocket dimensions and of the bridge dimensions for each model of bridge for those who want to make their own templates or program the pocket via CNC.

We also provide videos for the F&T model and G model installation. For the G model installation video, please note that some parts of the video show a dated method and obsolete tools. There is a note during this section of the video to refer to the G model template written instructions. The written instructions will always be the most up to date instrucations.

Otherwise, you can have your bridge installed through our INSTALLATION PROGRAM. To have someone else install in your area, see our list of installers.

If you encounter what you believe is spring noise coming from the bridge, be sure to mute the strings behind the nut with some foam, a clean cloth or a fretwrap and in almost all cases the noise should be gone entirely with the guitar being 100% silent. The EverTune comes with a built in damper and buffer system that will prevent any vibrations or sound energy from bleeding into the springs as well as custom dampening grease on all moving parts to guarantee 100% silent operation. We highly advise against stuffing any foam into the bridge as you risk wiping away the dampening grease which can cause mechanical noises to develop.

If you still encounter any other noises be sure to check for loose screws or parts, such as all screws on the EverTune bridge, the screws and height adjustment springs on the pickups and screws at the electronics cavity and input jack. If your issue still can't be resolved be sure to contact our customer service.

Currently the three major brands offering EverTune models from the factory are ESP, Washburn, and Framus guitars.

To become an installer listed on our website one must first do one install of any of our bridges.

The resources needed for installation we keep on this page. Here can be found the dimensioned diagrams of the bridge and the route pocket in the guitar, as well as written installation instructions. The files are in PDF, DXF, and STP format. Video routing and installation videos can be found here. [Please note, the G model installation video shows some dated tools that are no longer used. There is a note on the screen at these points to refer to the written instructions. The written instructions will always be the most up to date.]

To make the required route pocket in the guitar an installer can use a CNC machine or a handheld router with templates. Using our diagrams, an installer could make his/her own templates however we recommend buying the templates from us here. Our templates include all materials necessary to complete the route and they match our written instructions.

Expect a first time routing by hand to take 4 – 6 hours. Average price of an installation has ranged from $250 - $350 for the F & T installs and $300 - $500 for the G installs. A lot depends on the specifics of each install (was there a former trem pocket that needs to be filled, will the guitar need a recessed backplate because it is too thin). And ultimately pricing is up to the installer.

To be listed as an installer on our website, we need to know that the installer:

1. does clean routing for the route pocket
2. understands what makes a good installation in terms of the EverTune functionality
3. understands the setup and function of the bridge

---

To show us that the route is clean, please take before routing and after routing (without bridge installed to show the route pocket) pics of the front and back of the guitar and send them to cosmos@evertune.com.

---

Correct functionality of the EverTune means that:

1. each saddle holds contant tension in the range we call Zone 2.
2. each saddle has full range of motion for string height (action) and string length (intonation) adjustment.
3. the route pocket was placed in the right place so that the guitar can intonate properly.

---

The first video will show that each saddle holds constant tension. An example video is shown below.

And here is a written description of what the video should show:

The installer starts in Zone 2, then using the tuning pegs at the head stock drops down to Zone 1, then goes one turn back into Zone 2 and checks the tuning on a tuner. Then the installer goes all the way through Zone 2 to Zone 3. Then goes one turn back down to Zone 2 and checks the tuning on a tuner. The tuning at the point one turn from Zone 1 should be within 10 cents of the tuning at the point one turn from Zone 3

• In our example video we show only one saddle. The video the installer submits to us should show this test for all saddles.
• If the tuning varies by more than 10 cents on just ONE saddle, then it might be a defective saddle, which is rare, but it happens, and it should be replaced.
• If the tuning varies by more than 10 cents on ALL the saddles it means that the installation needs to be adjusted.
• If the note in Zone 2 close to Zone 1 is more than 10 cents lower than the note in Zone 2 close to Zone 3, then the front (closest to the nut) bottom section of the bridge needs to be mounted deaper into the guitar. This section rests on the footplate part, which is the stamped sheet metal part shown in the picture below.

• This footplate would have to be routed deeper into the guitar to correct the tuning when the note close to Zone 1 is lower than the note close to Zone 2. 1/8 inch (3mm) deeper equates to about 15-20 cents adjustment.
• If the note close to Zone 1 is more than 10 cents higher than the note close to Zone 3, then the footplate would have to be mounted less deep in the guitar to correct this issue. In this case, if the route is already too deep, the installer would have to use washers or a washer plate to move the footplate out of the route a bit. 1/8 inch (3mm) deeper equates to about 15-20 cents adjustment.

The second video shows that the saddles have full range of motion vertically and horizontally. An example video is shown below:

And here is a written description of what the video should show:

The installer starts with the saddle in the farthest forward position and the highest up positon.

In the video we tap the front of the saddle to show that there is almost no gap between the saddle and the front of the faceplate. This is the farthest forward position. Then we try to stick a piece of folded paper between the back top of the saddle and the bottom of the faceplate to show that the saddle is in the highest up position.

Then the installer drops the height of the saddle until the string rests or buzzes on the frets. This shows that the saddle can reach the lowest forward point.

Then the installer raises the saddle back to the highest position and pulls the saddle to the farthest back position. This shows that the saddle can reach the highest back position.

Then the installer lowers the saddle to the lowest position. This shows that the saddle can reach the lowest back position.

So essentially the video shows that each saddle has a full range of motion by showing that it can move to the four extreme points: front/top, front/bottom, back/bottom, back/top.

This should be done for each saddle. It is very important to a correct install because it will show if anything in the routing or wiring or pickups is in the way of the saddles range of motion.

If the action is unable to be raised so that the back of the saddle almost touches the bottom of the faceplate as in the video, and especially if this happens in the front most positions, it is probably because something is blocking the saddle from rising underneath. This can be wood from the routing that should be removed, wires, or even the bottom of thick pickups. Whatever is holding the saddle from rising, must be identified and corrected, before it can be considered a good EverTune install.

Likewise with intonation, if the saddle is unable to go to the far front position, something is blocking. The blockage must be identified and corrected before it is considered a good EverTune install.

The third installation video shows that the guitar is intonated correctly on every string. This will show that the bridge was placed in the right place relative to the scale length. This is very important because if the bridge is routed too far forward or backward it is almost impossible to correct this error and then the guitar will never intonate correctly.

---

To show us an understanding of bridge set up we ask for one last video.

Start with the B string tuned and intonated and set to bend. Then tune it down to an A and set it up so that it is again tuned and intonated and set to bend.

There is zero maintenance required with an EverTune bridge.

The bridge does come with some thick black damping grease installed on the bottom of each saddle near where the string goes through the back of the guitar. This damping grease is to prevent buzzing from the vibration of the free floating saddle. This grease should never be removed. It is almost impossible to reapply once the saddle is assembled.

If a saddle breaks for some reason (like someone overturns the hex key once it stops at the tuning limit and thus breaks the tuning screw) swapping out a new saddle is straightforward. The three videos below show the removal of both types of bridge and the swapping of saddles and re-installation.

When going from a higher to a lower string gauge, tune the strings to about a half step sharp of the desired note with the tuning pegs at the headstock. Then decrease the saddle tension with the hex key in the tuning hole behind the saddle until each string is in tune. This will avoid breaking strings by trying to get saddles into Zone 2 when the tension is set too high for the smaller string gauge.

CAUTION: Please note, if the hex key becomes hard to turn STOP TURNING IT, the tuners may have reached the end of their range. So if this happens, please contact us at info@evertune.com. We will respond promptly

Swapping out a new saddle is straightforward. The three videos below show the removal of both types of bridge and the swapping of saddles and re-installation.

Replacement parts are available here. We guarantee availability of replacement parts for 5 years after any version is obsoleted. We will try to make it longer if possible.

Every new EverTune guitar and EverTune bridge should come with a service pack containing an extra set of action screws and an EverTune hex key. If the installed set of action screws is 8mm then the service pack will have 10mm screws, if the installed set is 10mm then the service pack will have 8mm screws.

Every new EverTune guitar and EverTune bridge should also come with a printed Owners Manual.

Yes we do have custom longer action screws. The screws that come with the guitar are 8mm and 10mm long screws. We also have for sale in our parts store 13mm and 16mm long action screws.

We are in final prototype stage of our EverTune electric bass bridge. We are planning to have these available soon!

Right now we are developing prototypes for artists to test and approve. Development of non-digital equipment is a surprisingly long process and we know a lot of bass players have been very patient. The bass is turning out to be an evolution for EverTune, and we aim to make up for the lost time with extra functionality.

The next guitar version will most likely follow the release of the bass by one year. The evolution of the bass technology will most likely be integrated into the guitar, making it a faster development process.

We are cognizant of people who want EverTune now but also want the latest version, so we plan to have an adapter to be able to fit the new smaller bridge into the old EverTune route if possible. We also plan to give a steep discount to current original EverTune bridge owners if they decide to upgrade to the new version when it is released.

By popular demand, we will attempt to put tremolo functionality into our next guitar release. This release should follow the bass bridge release, which is the product we are currently developing.

We are very excited to release our acoustic EverTune bridges. We plan to develop this in parallel with our tremolo bridge.

Though it is impossible to say when it will come out, development on this iconic instrument should start right after the release of our next guitar version. It may be a few years before it is ready and it will be worth the wait.

We want EverTune to be an option for all stringed instruments, from violins to pianos to harps, etc. And some have even suggested for Drum heads! All of this takes time and engineering. First we have to cover our most popular markets: electric guitar, acoustic guitar, bass guitars and then we can move on to other instruments. The silver lining for the other instruments is that the product will keep improving as it develops so by the time it is ready for these instruments it will be the smallest size, lightest weight, and best performing product it can be!
