Beautiful hardwired amp by Jimmy Somma. Full/half power switch. Given the two volumes (Bright and Normal) and master volume, it's easy to dial in everything from pristine cleans to chewy Marshall-meets Vox type overdrive. I just received it, but have realized that once again I've overextended myself on the gear front, so here's your chance to get a like new R40 for a fraction of the new cost. The only flaw I can point to is that the LED on the Boost pedal isn't lighting up, but that's an easy fix and the pedal works flawlessly. This one is just like Jason Isbell's (Drive By Truckers, Jason Isbell), and he knows a bit about good tone!
