Okay, I understand that nowdays people don't like working with tools. Maybe it's because I'm an old guy, I don't get the "plug-n-play" mentality.
Everyone has their reasons. I've built every single PC I've ever owned and I consider that pretty easy yet some people are terrified to do the simplest thing like upgrade RAM or a hard drive. That's fine with me as people in the industry I work in are willing to pay me to consult. While changing a drive is easy, and while installing RAM is easy, sometimes making the right choices in a backup system might require a little more research. I have experience with this and that's some of the value that I offer to my clients when they hire me to consult. All they have to do is write a check and BANG, their problems are solved fast and efficiently.
My instructor has been playing bass professionally some 30 years or so. He teaches at Berklee College of Music full time, and gigs quite a bit. He also teaches outside of Berklee and one of his students is a rock star in a very major band that every single person on TB has heard of, the point being that the guy KNOWS his stuff. I'm sure he can set up his own instrument quite competently. Now consider that he has a wife and a kid and with his busy schedule I'm guessing the last thing he wants to be doing when he has free time is setting up his basses.
Another point I'd like to make is that everyone thinks they can be a rock star. I need to elaborate a bit. I have two businesses, a wedding photography business and a fine art printing business. While anybody can buy an expensive camera and have all the fancy tools, you can't buy experience. I don't care how much money you spend on equipment, I can do an objectively better job documenting a wedding with a point and shoot than you could with a $6000 DSLR because I have nearly 10 years of experience specifically shooting weddings. I've heard many a couple regret their decision to let Uncle Bob cover their wedding photos. As for printing... you can buy an inkjet and get decent results out of the box but, I literally have thousands and thousands of $$$ worth of hardware and software for calibrating my machines. I'm not using an out of the box setup. I have the tools and experience to do a better job than most photographers can do out of the box and for many pro photographers it's far more cost effective for them to pay me to deal with fine art prints than it is for them to do it themselves. Another analogy... I could go buy all of the equipment here:
gear
... but it wouldn't make me
sound like Steve Ray Vaughan. Experience counts for something. I've setup guitars before and I can do an okay job but a guy like Jim Mouradian can do a better job than I can on a full setup. His decades of experience are always going to trump my several years of experience. He's in demand... his setups are $85 and there's currently a little over a 1 month wait for an appointment to bring your instrument (where it's there for about 3 to 4 days). There's a couple of very major acts that have full time guitar techs on staff who drop all their stuff off at Jim's shop when they go through Boston. If everyone could do the same job with the degree of experience and skill he has, it's unlikely he'd be so darn busy.
Even if you buy the bass "off the rack" perfect, what do you do when you go change to your chosen favorite set of strings? Whine about the setup changing, go pay a tech to fix it? Really?
Good point but how often do you change the type of strings you play? Most people settle on something and use that for a long time. I'm going to be doing some string experimenting soon and I'll do some basic adjustments myself but once I've settled on something the bass goes to Mouradian Guitars for a setup.
If you're a serious player, some knowledge of how to set up and maintain your instrument should be part of the learning process.
I agree but that doesn't mean you HAVE to do it yourself all the time. I usually change the oil in my car. It takes 10 minutes and it's pretty darn easy but ya know.... sometimes I just don't feel like doing it (especially when the temp outside is *** below zero, I'll gladly pay someone else to do it

).
