Looks great.

I just finished swapping out the stock tuners on my JTV-59 CSB with the Schallers that were recommended here. It was a quick and painless process. No drilling, no exposed screw holes or issues. These Schallers are probably the best replacement you may find. They fit quite nicely.

The shafts are a bit shorter and remind me of the staft profile on the locking tuners on my Gretsch 6120 RHH guitar. The slightly shorter shaft make the string angle a bit changed, but no big deal. Also I notice the two top tuners, the D and G string are a bit closer to the headstock than the stock tuners. But again no issue at all. The new tuners are a bit heavier, but seem to be better made. The old tuners are made in China and the Schallers are made in Germany.

This is a no brainer and most anyone can swap these out with a screwdriver and pliers and a little patience. It sure makes changing strings on the JTV-59 way easier!

I suspect tuning stability will be improved and I thing it may have increased sustain a bit. I bought theses here:

http://www.themusiczoo.com/product/3184/All-Parts-Schaller-3x3-Locking-Tuners-Chrome/ at a good price. For some reason ordering them directly from AllParts was quite a bit more.

The great part is you can swap back to the stock tuners without a problem if you decide to.

Thanks to everyone who posted about these tuners and mak.ing finding these so easy!
