just in time for christmas, henry finished up my blackverb combo: what a beast! this thing begs to be cranked up. Very forward sound with plenty of punch. It took me a couple hours of playing and tweaking to find the sweet spots for my needs, because the amp has so many shades of gain based on the multiple stages of volume and gain control. It has input volume, which is global (feeds everything after), which then feeds into the OD section, which has the gain control, drive control, and level. Then it has the master volume, which feeds the loop, which has send and return controls. The return (when loop is engaged) is the real final master volume. Turning each one of these up or down in relation to one another (plus all the tone controls and toggle switches) can make for lots of variation in the nature of the overdrive. Then you have the mid boost and gain boost on top of that, in any combination. The beauty of this amp is that you can ultimately dial in a great clean sound with a ton of headroom, shimmer, and get it close to 'pushed', then use the footswitchable mid and gain boosts separate or together for slightly hairy or mild break-up tones. Then you can engage the OD and any combo of boosts for lots of variations from cranked tweed sounds to thick creamy overdrive. Plus it has a great buffered effects loop and reverb on top of all that. I will post more info and some clips very soon. Build quality is superb, loads of tonal options, very powerful, compact, and the tones are big and bold, yet smooth. I can't wait to get this on a a gig.
