Just got mine, compliments of Hello Music. Just been able to try it out solo'd, but so far pretty awesome stuff. I'll see how it fares at practice this weekend.
+1 to any post that said "wooly" or "one trick pony, but wow what a trick!" A/B'ing with plugging straight into the FX return shows that the preamp can be pretty clean, but again as others said not SWR crispness. (I'll A/B it with my SM-500 this weekend as well for that test.) A big surprise to me was when I EQ'd to 0-noon-0, it sounded very similar to plugging straight into the FX return. Not at all mid-ey, just normal. I haven't heard anyone mention similar results. I really liked the sound with noon-noon-9:00 (T-M-B), but putting the bass over 9:00 was waaay more boom than I'm used to/like. Uh, anybody else notice similar things?
I love the bite from my Jazz deluxe w/ .110 Roto's and this thing only adds to it. My comparison amp (Ampeg PB-250) tames it, but the BT lets it loose and adds to it. I did have a hard time getting a polite tone with it. I think it's there, but as soon as I hear that growl, my hands go straight to the gain for more. My guitarist was drooling by the end of it I think. Now to try it with the Muff --> Guv'na --> Fulltone Bass Drive for ultimate grind.
With the Gretsch, the pairing makes a monster. It does a great job at counteracting the pillowness of the hollow body. Doesn't hurt that it matches, too!
All that said, I'm not totally sold yet. I love simplicity, but this may be just too 1-dimensional. I do like variety sometimes and I play DB, too. I'm about to order a Tone Hammer 500 (and maaaybe the Streamliner 600) to pit the BT against for the Meanest Micro Awards. I've also really gotta get a more efficient / capable cab to make whichever I end up with really shine.
