Def spend a lot of time and money changing strings(at least 50 guitars, but who's counting?). I do (or my husband/kids) all the string changes/setups, so don't have $60-$100 bills or anything like that by taking them to a luthier. But yeah, I like having every tuning/tone on hand, so it's nice to just grab something ready to go.
Not much in the way of amps, an 82 or 83 JCM800, a JTM 45 reissue, a Twin Reverb RI, a Jazz Chorus, and a couple modeling combos. I mostly use a Spark 40 and Guitar Rig 6, though because I don't play out much... just don't tell anyone here

. I do like going over to the in laws though because we can crank up the Marshall and no one is around for miles. I really want to get a Fireball 100 for modern tightness after playing one, but I keep getting conflicting info about reliability and other issues. I'll probably just put it on my Christmas list, anyway.
