The little tab/alignment thingy busted clean off (see photo) one of my Sperzel locking tuners during installation last night. Any chance I can still use this tuner, or is it toast?
In a nutshell, the little guide holes I drilled were pretty damn tight, so pressing the tuners into place was quite a challenge, but I got all but one in. That particular one just would NOT go in, so after getting it about halfway in, I started working it back out (so that I could widen the hole a bit).
That's when the little thingy pulled right out of the tuner housing. I had to pull the tab out of the headstock with vice grips.
IMO you can still use that tuner. Just tighten the nut down a bit more when you put it on, and once it's in place I doubt it'll move all that much.
Sperzel's CS is awesome too btw, if you email them they'll probably just send you a new one. I had an inner pin snap on my Carvin and they hooked me up no questions asked.
