I've been having some issues with my SVT-VR recently and I've been using my Acoustic head as a backup through my 810 cab at band practice. This thing has been sounding EXCELLENT with a Pbass. Nice and fat low end and mids and highs that cut through without being harsh. I've had it cranked and it barely ever clips. For the longest time I was unhappy with it as a backup rig, but I had been playing it through a junk Legion Sound 410 cab. I'm really starting to like it enough to possibly start gigging with it when I don't feel like carrying my SVT. Just had to share my enthusiasm.
