OK. If anyone out there in TB-land is reading this thread and on the fence: Assuming you have the scratch, don't hesitate. Buy one.
Mine arrived yesterday and though I won't gig with it until Sat. 1/18, it's pretty clear during my time with it so far at home that I've been messing around with solid states and hybrids for too long. The articulation of every note with the 100T, the sheer impact, the warmth... well, it's the proverbial sound I've been hearing in my head.
I still like my Genz Benz Streamliner 900 and will use it sometimes, but I can see already it's instantly been relegated to backup status to the 100T. Again, we'll see how it does at the gig, but I couldn't be happier so far. And I've been playing on the 25W setting. The 100W is just too much in my house... literally shakes the windows.
I hadn't thought a tube amp was possible for me these days because of the weight. I'm 52 and though I'm in decent shape physically, I'm just not willing to lug an 80-pound amp. The 50-pound 100T is totally doable, however, and, so far anyway, seems sent from bass heaven.
