Your post resonates with my experience, and reminds me of a shift in my gear-buying proclivities that, now that I think about it, took place subconsciously maybe 15 years ago:
I used to buy gear -- especially pedals, but also some instruments and studio processors -- because I thought "that thing sounds cool...I'll get one, and then maybe if I'm lucky
I'll sound cool too."
But it seems like nowadays my thought process is more like "that thing sounds cool...
let's see if I can imagine how that might fit into my musical aesthetic." If I succeed in that thought-experiment, then I'll buy it (and hopefully sound cool too). But if I can't quickly begin to see how it might contribute to my palette in a creative and inspiring way, the GAS dissipates almost immediately, and I just return to the stuff I already own, the stuff that I already
know inspires me.
It might be slightly knee-jerk/impatient, but it does save me a lot of money.
