I have these in a 335 and they sound really tight and have very little character. Kind of like playing through a solid state amp. Not alot of sustain either. Almost no detail, dynamics, depth, rawness or vibe. They are very clear though with a sort of bell like clarity. The low E is what I would call piano like. And, yes I have adjusted the pickup heights quite a bit. Is this the way these are supposed to sound? I can't believe all the talk about 57 classics is based on this. Any feedback?
