I always thought "GAS" stood for Gear A-cquisition S-yndrome. In which case just about all of the posters have it. There is no cure. I have managed to control mine by buying little things when I get an urge for a new guitar--tuning forks, tuners, new strings to try out, etc. This, unfortunately only gives temporary relief and the danger of a relapse is always nearby.I had a friend who was a photographer and got got GAS in my sence. He opened up a used/vintage camera shop and never looked back. During the slump of the 80s when all photographers were going broke here in Sydney, he was sitting pretty.
Maybe, as Blind Blake and/or Blind Willie McTell say: "That'll never happen no more.
