I'm a bit late to the party here, but i'm doing OK for 2019 (compared to previous years)
Picked up a Yamaha RBX775 and an OLP MM22 on eBay within 2 weeks of each other for very good prices. The RBX was to 'replace' the one I've had since 2002 and effectively undo the custom defret, refin etc. OLP because I like 2 pickup Stingrays, but haven't the pocket for one.
I then sold my Dingwall NG3, as quite frankly it's 'too good' for my needs as a bedroom bassist and part time band member. I now have money back in my pocket and reassigned to a wedding.
I went through a bit of amp GAS a few weeks ago, then just picked up a Zoom B3N 2nd hand for £80, plenty to fix the cleanliness of my Trace Elliot Elf there. Sold a 7 string guitar too, don't miss it.
The GAS demon is a bit lost, it wants to encourage me to buy stuff, but there is nothing out there I actually want, let alone need, let alone afford.
My GAS solution as such, is have a few modestly priced instruments that are very different, the expensive ones give me anxiety and I grow to dislike them due to the inherent wasted capital.
