I did a shoot out.. WT400 against my Thunderfunk.. jazz bass through 2 TKS 1126 cabs
The Eden is warmer and fatter than the TF, the TF comes across as more focused low end and a little more defined. It didn't take too many tweaks to get them sounding quite similar..
In a nut shell, and as close as I can tell, the Eden has a bump at around 250, cut this frequency a little and its in Thunderfunk territory. That said, the Eden still has a warmth that I couldn't dial out. Another thing with the Eden is how little EQ is required. just a couple of clicks cut or boost really makes a difference. I really like it. With the 250 cut a little, I boosted just a smidge at around 1.2K and bit of treble (shelved at 2k) and it was snarly. I added a touch of bass, and it gave a terrific Pick tone. All flat, enhance at 12 and treble rolled off.. great dub type tone. The EQ will really deliver a wide array of tones, but always with that Eden warmth or thickness. I'm still surprised by how much I can crank the gain before the clip or compressor lights flicker. I can basically max it out, but It doesn't feel intuitive at all, so I back it off, but still play loads of gain into the pre amp.
I bought the WT400 really to satisfy the 'enthusiast' in me and intend to mainly use it at home, but tonight I will give it a run out with one of my side projects.. see how it fairs in a band rehearsal setting.
