Here are a few tips on TonePros® installation - you will probably want to print this page:

TonePros® Locking Studs Installation

First, in all TonePros® installations: Never Pull The Threaded Inserts Out Of Your Guitar! Your TonePros® components are designed to work with the existing threaded inserts on your guitar, and they should "dial right in" easily. Your components were shipped with inserts, they are extras and for use if you are building a guitar or other major applications. If for some unusual reason your components don't fit or don't screw in easily, don't force them, just click TonePros Help and they will help immediately!

Wrap-Around Bridge Application

Before starting the installation, first measure the height of your existing wraparound bridge as installed. Measure the distance between the guitar body & the top surface of the bottom flange of each stud that holds your bridge. This will save lots of needless height adjustment! Now remove strings being careful to hold the bridge while removing the last string. No crashes on the top please! Luckily, you will soon never have to worry about that again! Remove old studs. Now, dial in new locking stud bottoms, use your measurements to set height as before, as close as possible.
Adjusting bridge height	Now "dial" your new stud tops on lightly, hold your wrap-around bridge in place, and dial down the tops until they contact the top of the bridge, IMPORTANT ... do not tighten stud tops yet! Go ahead and restring your guitar, the tops of your studs should be contacting your bridge without any "leaning" yet be loose enough to allow you to adjust your intonation. Use the open end of your TonePros® wrench (12mm) to make any action or height adjustments.
Once completed, adjust intonation. When intonation adjustment is completed, use the handle of the TonePros® wrench sideways in the groove of the stud top to tighten, this should prevent any "screw driver marks" in the stud top. Firmly & smoothly tighten stud top being careful not to "over tighten".
TonePros® components are well constructed and will seat firmly and nicely, you will feel when it is tight & secure. WE ARE ALMOST DONE... this next step is important, now detune all of your strings so that there is no pitch present and give your stud tops a little extra snug tighten (this assures that the bridge is seated properly and removes any residual "lean"), now do your final intonation check/adjustment. That's it!! You are done, and it is set and will stay that way, strings or no strings!! Better contact, better transfer, better coupling, enjoy!	Tightening the locking studs

TonePros® Tune-O-Matic Installation

The first thing to remember, is that even though every company uses the exact same specifications, and we can "fly to the moon", we still can't always get our bridge post holes drilled in exactly the same, right places. You may not have noticed, but on many bridges, the hole on the bottom is bigger than the hole on the top, this is a "funnel or cone shaped" hole. This helps to guide your bridge posts if the holes are "just a little off". If your holes are just a little off, don't panic, your bridge will fit! And don't worry because "tight is good"! If the new bridge doesn't just drop right on at first, simply "dial up" your posts and either gently pinch or separate your posts until the new bridge is on and seats properly, then dial your posts back down to where you had them. Now restring your guitar as normal, and adjust bridge height as in the past. Once your "action" is adjusted to where you like it, go ahead and tighten the allen screws on each side bridge post (as always, careful not to over tighten) locking them in place. Now set your intonation. That's it!! You are done, and it is set and will stay that way, strings or no strings!! Better contact, better transfer, better coupling, enjoy!

Tailpiece or Locking Stud Insert Hole Size

IMPORTANT: TonePros accepts no responsibility for drill bit choices and/or installation methods and ALWAYS recommends using a professional who is skilled in this procedure for installation. TonePros cannot be held responsible in any way for errors and/or workmanship issues in the installation of any product.
The most common drill bit sizes used for tailpiece stud insert holes are 27/64ths and 7/16ths, each builder has a favorite size & method they typically use. Metric size bits of 11mm's are also commonly used. As drill quality and size vary, TonePros ALWAYS recommends using a micrometer to measure insert & drill bit size to assure a match before drilling any holes, and a "test hole" in a piece of scrap wood prior to any installation to check for fit is suggested. The method of installation also governs the choice of bit used (press installation, rubber hammer installation, etc). Please note, this is not a "do it yourself" type of operation, please seek professional help or advice before starting any installation procedure of this type.
