well, hoping one of you knowledgeable fellows will be able to help me! ;)
i have a couple of Gibson guitars that require truss rod adjustment. on other guiars i've been able to use an allen key, but not on these. it seems to require some sort of spanner. anyway, i went to Allparts site to see about getting one, but there are several different sizes. could anyone tell me which size would be right for a Gibson? assuming of course all Gibsons use the same size?
thanks ;)
