thanks for that.they look quite similar to the 2nd set of grovers there except they dont have the 2 screw holes in the back or the grover script ,schallers maybe?i have found a broken tuner i my parts box - the threaded bit that goes through the headstock looks ok so im going to try combining the parts and see how that goes for this weeks rehearsal.a new set of tuners is probably a damn fine idea though.
