I always had bands from the age of about 13 ( first bar gigs when I was 15) until about 10 years ago when I hung it up. I seemed to always start 3 piece bands or bands with only one guitarist anyway. I'm a bassist by the way.
About 8 years ago I sold off about 30k worth of PA gear, lighting, 16' customized, enclosed trailer, spare amps, cabs, etc..
At one point I had 3 full SVT rigs.
What's left ? About 10 guitars, 15 or so basses, one full SVT II non pro/810cl rig, GK full stack, Boss Tuner pedal, Ibanez Flanger, TAFM, 1961 Fender Brown Deluxe ( with Alnico Cream 90 and Blackplates), Chinese Vox AC-10c and 6 or 7 MXR Distortion + pedals of varying vintages.
All of the guitars kind of have sentimental value so I don't think I could get rid of them. I have 4 basses I'll never sell, the rest could go. Mostly Fenders.
