Ha, the original poster asks if his Hartke combo is good enough... Considering James Genus uses nothing but a little Hartke combo on Saturday Night Live, and he sounds as though every note is crafted by angels of bass tone, I'd say it could do the job

Of course my good home speakers, a good sound guy and oh yeah, a good player doesn't hurt.
I'm personally always tinkering. I only use one bass almost all the time, my Schack that I've totally modded, but the amp is tougher. I've always loved a pristine, dry, solid state tone, but never quite got that out of gear available years ago. Now with the class D trend and super tightly built speakers, I'm finally starting to hear the tone I've always wanted. I currently use an old solid state Yamaha PB1 pre, an older crown power amp from the made in USA days, and a bag end 15. It's very pleasant, band mates and sound guys love it, but it's heavy to drag around and not crisp (no tweeter). I played a Phil Jones combo and some Epifani/Bergantino combinations recently, and the TC 750 head, I just can't decide. They're all so good, so tight, not at all brittle, exactly what I want, it's just a matter of taste now. Funny thing is some amps are actually too crystal clear for me now, I thought I would love EA heads based on a few reviews and friends' recommendations, but I found them to be harsh and unforgiving. I told the sales guy I don't think I'm a good enough player for EA

one of these years... I wish I knew where to try out a Thunderfunk... Make it stop!!
