  1. I just installed string butler on my Gibson SG that would not stay in tune, and now I’m jumping for joy! My guitar would not stay in tune for anything. Well, it would be ok with Nut sauce, or pencil graphite but would not last. After I installed the butler, and reset my strings, I played for maybe an hour, and stretched my strings to the limit! they stayed in tune. Now my Gibson SG sounds as good as a PRS, or any Guitar I have ever played before. I woke up this morning, grabbed my Guitar and jammed and its still in tune! I love you guys. I need another one for my Taylor Big Baby Acoustic but I cannot install it he way you want me to because the truss rod cover is in the way, so ill install it like I did on my SG. I don’t see any reason why it wont work installed that way. Thanks, I’m very happy.

    1. You helped me finally get the guitar I wanted when I bought my Gibson LP Standard. Thank you for a good experience!

  2. I got a wonderful deal on a 2013 signature t brand new in the box directly from Gibson deal of a lifetime was like buying a standard for $1000 dollars the only thing was that it had a grenadillo fretboard great guitar but of course it would not stay in tune literally if I was breathing on it it would go out of tune I was getting frustrated that’s your product yesterday installed it and with that straight hang I’m going to Echo one of the comments it’s like I own a PRS thank you very much gentlemen I think Gibson should have these installed on all their guitars straight from the factory that would be a nice account!

      1. I have a Korean Gretsch 5420. What tuber adapter and string butler model do I need? 53mm between tuning posts.

      2. Hello,

        The post separation calls for a V3. That headstock must be smaller than some of the other Gretsch that use a V4. Does this have the Vintage Tuners (no hex around the base of the tuner post)? If so, then this could be tricky. The Vintage Adapter Kit 1 one might work but I’m not sure. The bushings vary a lot between guitar models. Our bushings might be too large. You would have to take one of your bushings out and measure the diameter of the spline area. If you have the hex around the post then all you need is V3 and you are good to go.


    1. Hello Norm,

      Yes it works with acoustic guitars. In some cases, if the truss rod plate is oversized, you just need to mount it inverted between the A and B string posts. The V2 or V3 should fit.

  3. Hi there! I’m interested to tryout your product! Which one will fit best my Lespaul traditional? V3 or V4. It doesn’t have vintage tuners. I think it’s a 2012 and I want everything black. No chrome at all
    Thanks 🙂

  4. Hi! I have an Epiphone G-400 Pro SG (2019) guitar with the stock Wilkinson tuners (planning to buy Gotoh SD90 MG-T locking tuners to replace the stock ones). If i order the V3 string butler, should i order an adapter kit too? If i should, which one? 1 or 2 kit? (i don’t want to replace the new Gotoh tuners if i will have them) Thank You in advice! Gabor

  5. Hello Gabor,

    Many, if not all, Gotoh tuners have oversized tuner post diameters. Our adapter kit one only works with posts that have a diameter of 6.15mm or less and since this is a vintage tuner with press-in bushings that you are looking at, you would need an adapter kit. However, this Gotoh tuner model has a diameter of 6.35mm which means the post won’t fit through our bushing. When buying tuners that are compatible with the String Butler, if you go with threaded bushings, you also need to look at the diameter of the bushing to ensure that it isn’t greater than 8mm as this is the width of the String Butler in the area that goes around the threaded bushing. Some tuner models have oversized threaded bushings as well.

    Hope this helps. Technical info on our adapter kit 1:

    1. Thank you! And what if i don’t buy the gotoh tuner set? will the V3 + adapter kit work with my stock tuners? if it will, adapter 1 or 2?

  6. I have a 2014 Gibson ES 335 with the same tuning issues. Which kit String Butler should I get, Thanks!

    1. Hello William,

      The V3 will fit. The V2 might also fit. However, you might need an adapter kit. Please locate the FAQ on our website and it will walk you through to determine. Email at if you need more assistance.

  7. Thanks Danny, I believe the V3 and V2 will work fine. I have Grover locking tuners on my ES, thanks again for the direction.
