I always check out ALL the gear. Bass, guitar, drums, PA..... learning, learning. .....
I hate gear snobs. ..Once, a guy I liked. ..a local bassist. . told me- at a gig where I was playing with my Stingray 5...- that you HAD to have a $800 + bass to gig with or it'll just sound cr@ppy. So for the next set, I used my $150 modded SX P bass


& it, of course, sounded great. I didn't say anything to him tho.
When I'm impressed by a bassist's tone I'll have a good look'n see what his chain of events is.
One that surprised me was a LMII into a Mark Bass 104HF that wasn't going thru the FOH PA but filled the room beautifully.
Another was a LOUD international alt rock band that was playing in the club that my band plays monthly.
They were LOUD as hayull.!!!!! Both guitarists had Fender 410 Bassmans and the bassist had a vintage Fender Bassman 100 running into an Ampeg 810AV - sure it was mic'd to the PA but it sounded effin great and must've had enough stage volume to be "there" for him with those guitarists amps cranking out power tube distortion.
