But does it really matter if the musician can tell? He is STILL going to rock that schit anyways.....Give Jimi Hendrix a beginner pack guitar from GC, he'll make that schit sound like a million dollars.....Give Ray Charles a Yamaha keyboard from Walmart.....He will still rock it like Ray Charles....It's about the man, not the equipment....
It matters to the musician, and if you're a musician, you do care.
As for your other statements regarding Jimi and ray, I'll have to take your word for it, cuz I've never heard them sound great on cheap gear, seeing them at all would be a privilage, but I'm doubting you ever saw them rock cheap gear and it is pure conjecture.
You are still looking at it from the perspective of the audience. Jimi hendrix went through a bunch of Wah wah's from the same company before he picked the one he wanted. He could have used a lefty strat after he got big but he preferred the righty one backwards for more than just a trademark look (it has to do with the rear pick up and tremelo arm position) Sure he could have done it with a les paul or whatever, but as a musician, he had a preference. In fact you rarely saw him with any variation in his set up, which might lead one to say that part of his skill as a guitarist was knowing what worked for what he was after.
that is what people talk about when it comes to gear, a musician's preference, most musician's I know have preferences and many of those preferences have an effect on their performance.
now i assume when I come here I am talking with other musicians, but with the MPC series being so popular with DJ's and beginners, dare i say wanna be's, many people are more along the lines of musical consumers, and on that aspect i feel you, where people act like the right purchase will make their music better without puttin anytime into practicing any skills. In that regard a lot of time is wasted.
it;s all summed up in this statement
you can't escape that the musician's experience counts, not just the listeners experience.
