First off, Ed Goode, thank you for the nice compliment. I don't view my thoughts as gospel by any means, but I have been in many different pro situations, and though most of the time nobody tells me what bass I should play, there are some times that I'm requested to play a certain bass, and 99% of the time it's a Fender.
I am by no means even close to the world's greatest bassist. But I'm never without work. Why? Mostly because I sing pretty well. But it's also because I'm easy to get along with and willing to work with other people's requests within reason. I don't take crap like getting jerked around, but I am very easy to get along with, and if someone says to me, "Hey, I love that Jazz Bass of yours," or "Hey, a lot of our stuff requires some low notes so if you have a 5 or 6-string, bring it," I make sure every time I work with them I bring that bass. I see nothing wrong with making the guy paying you glad he hired you.
Apparently some of you have a problem with that concept and think that your talent wil overcome everything. It won't. I don't care who you are or what you do, your talent will at some point be meaningless to someone who hires you. If you play music as a pro for long, at some point you will get someone who wants to hire you because they want a project done the way they want it done and they don't care in the least about your talent or your opinion of your equipment. And it's usually the gigs that have the least freedom that pay the best. You want to walk away from it, that's your deal. Me, I can't afford to walk away from it. I'll do everything they ask to the best of my ability. Wanna call me a sellout, you go right ahead. I'll see you at the bank.
Let me ask a hypothetical of the people who think that's selling out...someone calls you and says they heard you were a great bassist and they have a session they want you to play and it pays $200 an hour with an eight hour guarantee, but when you get there with your wonderful $5000 Fodera and your $3000 Sadowsky and your whatever, there's some old dilapidated 1960's Teisco bass with the original strings that the producer absolutely loves and wants you to play and he doesn't want to hear from your basses. Do you insist on using your bass and he throws you out and hires someone else, or do you pick up the Teisco and make your $1600? If you say you'd insist on using your bass, I'll call you a moron to your face.
