My questions to the collective:
1. Do you advertently or inadvertently have a gear bias?
2. What is it based upon?
3. Who are some other pro-level artists that routinely use "entry" to "mid-level" gear?
1. I've tried not to have one, because experience has taught me much like you; musical talent and technical skill has no inherent or innate connection to cost of gear. I've had players with $600 worth of gear blow me away both technically and sonically, and I've had players bring $6,000 worth of gear and proceed to squat down and lay a nice fat coil on the stage. Musicians come in all types and at all income levels, whether they make their living on stage or not.
2. My biggest gear bias is with amps, mostly because they cause the biggest problems for me both as a sound engineer and as a casual listener. It's not so much how cheap or expensive, but your wattage, speakers and connections. Bringing too much
or too little rig for the gig causes headaches of different kinds, and speaks volumes to your experience and professionalism as a musician. I honestly could care less which axe you plug in, I've seen and heard just about everything sound good, and bad, with price being little determinant. The loudbox on stage, that's usually where you and I are gonna have a problem, if we do.
3. Not new, but there's a video of a jam session where Victor Wooten, known for his $15,000 Foderas, rocks a sub-grand Sire V7 instead:
... and he's a Hartke artist, which is a brand I've never really considered high-end, though it appears they certainly can be these days.
