Fender T-Style Truss Rod Adjustment Wrench, 3/16in, Red

Right tool for the job - great quality and very robust!

Works as expected on my early 2000s American precision bass. Now all I have to do is get rid of the bogus s1 switch.

Works on my Fender Player Plus Percision Bass with no issues.

Works as intended

First, I should say that I probably could have saved the money. I had converted my 5 String Marcus Miller Signature Jazz Bass to 'Piccolo' (tuned to A D G C F, with only the low 'A' String being lower than Guitar Tuning), but those much lighter strings need to be tuned to a higher tension which pulled the neck forward, so THAT called for a Truss Rod Adjustment. So I ran to the computer and ordered this shiny new Truss Rod Wrench before remembering that I already had one in the case, stuck back in the closet. Also, when looking at the design of this truss rod wrench, with its small slippery grip that hardly fills the whole fist, well, you have to remember what a Truss Rod Adjust is doing -- you are flexing a Big Piece of Wood back, and that comes with a great deal of resistance! So when I made my adjustment I simply wrapped a handkerchief over the little red handle and cranked as hard as I could, and found that I had cranked it far enough (sometimes it doesn't take much to make a big difference) to get the adjustment very close to nominal, but it would have been easier to get two short pieces of pipe to slip over the handle ends to use as 'helpers' for added leverage, and then I could have used both hands to crank up the adjustment. . Oh, just for general information, when I was researching to find what size Wrench the 'MM' required, I found that not ALL Fender Basses use the 3/16" size wrench... apparently some of the Squires use 5/32" I believe. But if you own an American Made Fender Jazz Bass with the adjust at the bottom of the neck, accessible through a cutout relief in the pick guard, then this 3/16 Wrench should probably do the trick. Oh, and if you never did a Truss Rod Adjust before, remember the few provisos and cautions involved -- if the neck is too far bent up and forward making the neck bowed like it could collect water in the middle (your Hint that you may have a problem here is that your strings are 'buzzing' on the lower frets, but adjusting the strings up from the Bridge makes the 'Action' way too high in the middle of the neck), then the Truss Rod Adjust will be Twisting Clockwise which will tighten the Truss Rod to pull the Neck Back. You HAVE TO LOOSEN the Strings before you do this! The Adjust is stiff enough and will fight you plenty without having to pull back against the tension of the strings too. And while we are on the subject, especially with a Neck as long as a Bass Neck, you must have the strings tuned up to check the Adjustment, because without any string tension at all, of course the Neck will snap back. Now If the neck is pulled too far back (your Hint here that you have a problem is that strings buzz on frets in the middle of the neck) so that the strings are down too close to the frets on the middle of the Neck, then you can make the Adjustment Counter-Clockwise which is a great deal easier, and you can do that adjustment with the strings tuned up, as the pull of the strings will actually kind of help out, as the pull is in the same direction. Oh, here is a Tip -- If you have to make the Clockwise Adjust to Tighten the Truss Rod and the Adjuster doesn't seem to want to move, and it is an Old Bass, well, to make sure the Adjustment Bar isn't old and rusted solid on the Nut, then instead of turning Clockwise, turn it Counter-clockwise just to see if it will budge. Remember, you are trying to bend a big piece of wood, and so you can't expect it to be easy. And, sometimes just One-Eighth of a turn is all you need. In Truss Rod Adjustments, A Little Can Do A Lot. Oh, and don't expect a Truss Rod Adjustment to be a five minute job. You might have to go through the cycle of loosening the strings, cranking some adjustment in, retuning and re-checking several times before you are finally Happy. But 20 minutes should do it. Just be glad you don't have the kind of bass that requires you to remove the neck to make the Truss Rod adjustment.

My main complaint is that they don't make these in all truss rod sizes! Just this one that I'm aware!

It works with my Player Series Strat neck, and I'm happy, what more is there to say?

This will last forever, right tool for the right job, jut would be nice if it came with some of the higher end Fenders, although there are at least three different ways to adujust fender necks, so it's not universal, and it did not fit the sqier jazz 5 string. Fits MIM P bass, 2018 for sure.
