getting a good tone on a certain piece of equipment, perhaps even recording it down, and then forgetting what you did exactly, and never getting that tone again? makes me utter mad...
argh, for me it's harder, I come from israel, it's the slut house for guitaristsuke:, everybody uses everybody elses equipment, right now I have at home my own guitar and another 2 guitars each belong to 2 friends of mine , and a jekyll and hyde pedal I stole from my rhythm guitarist the rehearsal room in the area also keeps switching the heads between a mesa dual rectifier and a JCM900, and sometimes you get pushed to using some weird yamaha tube head which I don't know where the hell it came from also each concert we have the same 10 bands which switch up the same POD/distortion pedal/octaver/whatever the hell some guy found the willpower to carry with him and not borrow from somebody else
