GAS is curable, and I'm pretty sure of this, but all the funds these days are going to what is considered more important medical research. So I think we must rather live _with_ it than against it.
That aside, for me GAS is about curiosity, and a feeling of needing to know how different pups, necks, strings, pup placements, etc.etc. are.
I feel I have to have experienced, thoroughly, some different necks dimensions, string spacings, materials used, etc. before settling for a tiny collection of gear I love more than the rest.
I think the core of my GAS is a lack of knowledge.
Also, for 300 quid, I can hang a print of an unknown artist on the wall, or a quite nice bass. A no-brainer.
best,
