I don't know @outoftune. I have been thru the GAS and out of GAS. All I can say is the best way to beat it - if you want to/this worked for me is to follow this:
1. Is something truly broken, as in, is this a show-stopper emergency. If so, you gotta do what you gotta do.
2. Unless it's 1. above, must have financing in place first. No credit. possible exception is the X number of days, same as cash deals that would be your call/your budget.
3. This one is tough. Make yourself wait 30 days. If you are still all about it a month later, it must really be a thing and should be addressed. See 1. and 2. above then proceed. - An optional add-on might be to make yourself learn something that will improve your bass skills before you "let" yourself buy a piece of gear. I've done that one too.
So far I've beaten the GAS this whole year, save the KZ-6 IEMs that I bought for my Church gig. It's the only thing I have going that uses IEMs and they provided some Behrenger's that worked for everyone but me. On those bass=mud, so that survived my 1. test. My goal is to buy nothing apart from strings and necessary maintenance for the balance of 2019. Wish me luck!!
