Greetings. Newb here So I found this basket case Epi EB-3 over at Reverb. Needs some parts but it will be OK. Got a new DiMarzio PU and a HipShot SuperTone on the way. Here is what I found that makes me wonder. The Bass has black Tuners and a black 3 point bridge. The Tuners are black SCHALLER'S, that are engraved. That's a German make used by Gibson, but with a Gibson logo on it..The serial number is sanded out, but there is a Stamp on the head stock that looks like US.. and I can't see what it is. Maybe numbers? Anybody have an idea what this is ? I post some shots once its all together. Thanx for your attention.
