Ignoring all the MAB talk before I join in to mock his wig: GAS is really just a distraction. I often find myself thinking about getting new stuff although I actually have everything I'll ever need instead of just sitting down and practicing. Heck if I only had my Micro Terror Head + the small PPC 108 cab with the Bad Monkey and my first guitar, it would be enough. :lol:
I found a good way to ignore it though: just sit down and practice everytime GAS hits you. Save a 100 quid every once in a while putting it somewhere you're not urged to grab em the next day again and eventually over the course of time you'll have enough cash to make a decent purchase whilst you're not rushing to get some cheap stuff you eventually will never need. It's just letting go of the thought that it could always be better, it's your fingers that do the talking, gear is just 10%. It's hard, but it can work ^^
