I'd like to hear some more rhythm playing too, but in the 1979 vid I dig that bend you hold out and let scream. That alone tells me a lot about the overall sound/capabilities of the amp. Well done!
I've never tried it (two overdrives) but there's at least a couple guys between here and the Guitar Gear forum that double boost. I remember hearing a few clips of a Henning Cherry Bomb with two overdrives that sounded pretty sweet.
Thanks dude, I'll check into all of the above. Going to do some shopping this weekend for OTFs and maybe some trench knives. I've had an old knuckle duster shank since the late 80s, but I'd really like another one with a skull crusher pommel. Leaning towards ordering a 1918 US reproduction...
