This will be a "d'oh!" thread for many of you, especially the GAS-sy types, but I just *got* it. I've always believed that I should be able to get everything I want out of a single bass. For a long time it was a fretted Tobias, and it did, in fact, do everything I needed. Then I started playing fretless, and got a Willis (Ibby GWB-1). Great sound, but not quite what I heard in my head. Put an ACG preamp in it - even better. But I played a Zon and wow! I had to have one. So I've mostly been playing the Zon, in a context where I'm playing melodic support behind a singer-songwriter. That bass works great, and it's THE sound for me in that context. I kept playing the Ibby because it's fun and also sounds good, but the Zon's been winning and getting to go to the gigs. Until - I've started getting some R&B gigs, and have an audition with a funk band tonight. The Zon is, well, polite and pretty. The Ibby/ACG just SNARLS with what is, for me, a perfect funky fretless tone. Wow. Each bass shines in its own context. Both can handle each context, but I can honestly say I prefer each of them in different ways. So I hereby renounce my "one bass can do it all, and I should find one and be happy with it". Bass polygamy is OK.
