Keep them if you can, I thought I'd found "the one" when I got my TM5, then after a few weeks of gigging I decided I didn't like the pre-amp, not a big problem, but now, a few months down the line, I've decided the humbuckers is in the wrong place, I still love it as a jazz bass, but I'm really glad I kept my stingray, because I couldn't do without that sound in my life.
