As are all things in life, it's just about perspective, and how we were conditioned growing up. Our perspectives on money, materialism, desire, and attachment to "things". I have been a gearhead for over 50 years. If it wasn't basses, it was keyboards, amps, audiophile stereo gear, cameras, and even tools. I like things, and I like to know how they work. So I build furniture, I build basses and guitars, and I've helped build companies.
I'm also a history buff, and music gear is a vehicle for exploring the history of one of humankind's most mystical and universal languages: Music. On the more mundane level, I love trying out new things, and learning about them. So I endeavor to try as many basses as i can, in order to discover those that may find their way into my heart and mind the most.
I am starting to learn a lesson ( for myself ) about the affliction of GAS. I have found that it can be very powerful to try basses that the "pros" or the snobs often cite as the best. It puts my whole collection to the test. For instance, once I allowed myself to purchase a fantastic pre-CBS P bass, my GAS has significantly decreased. As a lover of vintage basses, and not so much modern boutique basses ( lucky ), I used to dream, and frankly torture myself about wanting to buy CS basses, Moollons, Olintos, Lull, Alleva-Coppolo, etc. I finally just did it. It helped my GAS immensely. Then finally the real 50's P. It's the best, and it actually plays and sounds the best of my P basses. Not mind games, just feel and sound. That even put the Mollons, Olintos, and Alleva into a new light. A much less bright light. I think sometimes, if you have and you understand your tendencies, your desires, and have full awareness of the role they play in your personality, perspectives, and motivation, you might do best to indulge your desires for gear to the extent you are able. I envy those here that are completely satisfied with their one or two basses, as they see them as tools, or simply that a few basses meet all of their needs and desires.
I'm just not that way, and someday in the not too distant future, I will be moving my collection along to the next bassist who desires something that I valued so much.....and on and on...thanks for indulging.
