I found different amp settings that I liked for each guitar, and I put a little different coloured dot sticker beside the knobs at the positions I liked (Blue for the Strat, Red for the Ibanez, Yellow for the LP copy.) Same for the couple pedals I used. (The dots had a pen line in the middle, to make it easy to dial in.)

Oh and really the only other bit of useful advice I have to offer is... always set your beer on the bass cabinet. If in a two guitar band always encourage the other guitar player to do so as well. Usually the bass cab is higher, thus more convenient, and once you establish it as the beer table, you won't have to worry about your amp getting filthy.
