Apologies in advance. I know the "tell me what I should buy" subject is boring, and I'm sure this post will be long and rambling. That said, I'd really appreciate some opinions here. I've already searched the archives, but first-hand accounts on the tone of these amps are hard to come by. If nothing else, it helps my decision making process to get this stuff written down. Ok, right now I'm running a Dingwall ABI 5-string into a G-K 700RB with Avatar 2x10" + 1x15" cabs. I've been psyching myself up to sell the G-K for a while now, and I'm getting pretty close. The reason is that the Dingwall is a very bright bass by nature, and I'm having trouble taming it with this rig. I feel like that G-K is a naturally "snappy" amp, and I'd like to find something a little warmer with more low-mid "punch." My price range is about $600 or less (new or used), and I've pretty much narrowed it down to the Kustom or a used Eden WT-400. I'm leaning towards the Eden, given its reputation as a warm but modern sounding amp. But the lure of huge watts is hard to resist. My 700RB gets plenty loud for me, and both the Eden and the Kustom are more powerful, so I know either one will be fine for my current cabs. At some point, though, I'd like to upgrade to a Schroeder 21012, and, given what I know about the inherent trade-offs in speaker design, I'm worried that I may want more power than the Eden has. This cabinet upgrade will be a while from now, so I should probably just cross that bridge when I get to it. For the short term, I think I'm going to swap the 15" for a 2x12". Besides the power issue, the Eden seems to be more in line with my needs. I have yet to try one in person, but the tone controls seem really simple and flexible. The Eden's small size and portability a definite pluses, too. On the other hand, the Kustom seems to be pretty configurable with it's shift-able tone controls and 9-band eq. So... ideas?
