Coil cords - I use them! Vox makes some really solid ones these days in funky colors.
I played my Sunn Enforcer last night at pactice running it through an Orange PPC412 - brought the doom like a sunn of a biotch. Volume was good, but as much as I thought it would be dimed though, my Orange and Marshall are both louder. But it was not lacking (we play stupid loud so it was fine, in fact we are starting to turn it down so we can hear the singer through the PA and we even drown out the drummer sometimes lol), kept up with a dimed Matamp GTO120, really from 5 to 10 it didn't get me much more volume, my Beta Lead is the same way, gets really loud fast then tapers off. Tones: dark, doomy, vintage, heavy and growly. I blended both channels (like I do on my Beta Lead) for ultimate tones. It is the best sounding amp I have for the doom stuff we do. We started out as a doom band and still play a bunch of that stuff but we are slowly moving more into the stoner rock side of things, our new song for instance sounds like a Clutch song and we have several that are Kyuss influenced.
