I'm looking to replace my Eden WT-600, and here are the candidates so far: 1. Genz Benz GBE1200 - I like the idea of having two channels EQ'd differently, switching and mixing. The LEDs seem a bit over the top to me, but I could live with that. 2. Thunderfunk TFB750-A - this is a strong contender at the moment. What are the cons if any? 3. Ashdown MK-500 - I've used graphic EQs a lot over the years, and really like them. IMO they provide better mid range control, but like I said, that's what I'm used to. I've seen some complaints about noise re this amp? 4. Gallien Kruger 1001RB-II - I know absolutely nothing about GKs, never ever played through one. People here seem to like them... The Eden adds a bit too much color for my taste, and I'd like a tighter low end as well. That's why I will be replacing it. All the four amps above are roughly the same $ here. A tube pre is really no big deal to me, I prefer a clean sound. Tight, controlled lows and mids are important, as well as headroom. The problem is, I'm not able to test drive any of these. The amp will be driving a Schroeder 610L @ 6 Ohms. Any input appreciated, thanks.
