Well, I Played a gig last night with the 550 and the el whappo! We played two sets of original rock/jazz/funk, the first set I used the Tfunk, and the second set I used the HBP-1>Crest Vs650 setup.
I was liking the T-funk a lot. It is so loud! The tone shaping options are so well thought out too. Between the timbre and enhance knob, I really didn't need to use the actual EQ, besides goosing the bass knob a little. I thought all in all, it sounded great. It's clean, it cuts through really well and it's loud as hell. Then I plugged in the rack setup for the second set... and the Demeter is just undeniable. There is a definite clarity characteristic that I love about that rig that the T-funk couldn't quite hit. It's some kind of tone that is not neccesarily EQ related, just the sound of the circuitry. The Demeter is really pristine and super quick, especially for a tube pre, and the T-funk did not seem to have that quickness, which was noticeable especially when slapping.
I'm not saying at all that I disliked the T-funk. I was really impressed with it as a whole, with it's power and versatility. I just really dig that pristine quickness and depth that the demeter has, and I couldn't get there with the T-funk. It's a tough decision about what to keep, The demeter isn't nearly as flexible, but what it does, it does so well. I sure wouldn't mind shaving 30 pounds and 2 rackspaces off the rig.
Tommixx, we talked about these two rigs, does this jive with your experiences at all?
