Guess I'm in the no-lube camp. That said, I've never been a pro and my gear has never been tested to that degree. Most gigging I've done has been as a weekend warrior (4 weekends/month). My kit has never seen anymore action than that. So, re-tuning problems have usually been overcome in a jam/rehearsal situation. Even the resto I'm doing on an early 70's Gretsch kit will go back together, with whatever residual lube that may be present from the factory. The next owner can decide on lubrication.

PS - My un-lubed gigging Gretsch kit is of a '74-ish vintage. Owned it since '78 and never thought of lubrication. Am I a bad owner?
