There is a Tube Works head I've been contemplating on buying, but I can't find very much objective opinion on the sound of the amp, beside the one H-C review. Any experiences/opinions on these amps? Power? (Etc.) I play a passive Kawai (P pickup) through a BDDI into a Yorkvile combo right now. We play a wide variety of covers from country to rock, to R&B/soul, if that helps. I like old Motown-y types of tones, not big into hi-fi or zing. I'd be going through an Avatar 1x15 cab for most of my gigs, if I went through with this purchase. Not really high volume, small places. You know, typical Cleveland bar band. Thanks in advance.
