How reliable is the Crate Powerblock? I think for me overall it appears to be the best choice for most of the gigs I'll be doing, but I'm concerned about using it as my sole amp. I have small class D stereo amp that sounds good but intermittently cuts out (some digital weirdness), and I suspect to meet the price point the pots and connections in the PB are not exactly top of the line. That said, it wouldn't be knocked around much, so as long as its not TOO cheesy in interior build quality it might be okay. Assuming the tone quality stays fairly consistent when you turn it up (I played one at moderate volume and like the way it sounds, but haven't used one at band volumes) I think I'm cool with the tone. Anybody out there with lots of road miles on their Crate PB?
