This is nothing new... we all just like having cool things to brag to our musician friends about, or to talk about on forums.
I spent over a decade hitting stages with high-end amplifiers, speakers, and basses. After taking a couple years off and selling off all my expensive gear, I started playing in a band again using a Peavey Session Bass head. I got it on eBay for $130 shipped. I said to myself "Jesus, I can't be using this thing with a band, right?! It'll just hold me over until I get something nice" and then I started playing shows with it, and realized no one ever commented about the amp I was using, or the tone I was getting. You're right, no one cares.
That was 2008. It's 7 years later, and I'm still using the same amp and the same pair of 90s Genz-Benz 210 cabs, and I've never had anyone comment about any of it. I like having a nice bass because of how they feel and play, but the audience doesn't know the difference between the Streamer Stage II 5-string that cost me $3000 used and the Fender Modern Player Jazz 5 that cost me $400 new. The Fender says "Fender", so bandmates like it better, soundguys at shows like it better, and recording engineers like it better. Give Victor Wooten a Rogue bass from Craigslist and he will still sound like Victor Wooten. Give me a $10k Fodera and I won't sound like I deserve that bass! LoL
Gear is the way we reward ourselves for our dedication to the craft. If I were rich, I'd probably have an expensive car. Would it be more reliable than my Camry? Doubtful! But it would be a tangible representation of feeling a sense of accomplishment.
The only problem is when you choose to have expensive gear while your family struggles to make ends meet. But as long as you're taking care of things, if you can amass a collection of jaw-dropping gear, good for you! I'm all for it.
Happy GASing!
