Fantastic bass head, perfect for anyone who wants the ability to dial in a nearly infinite amount of Mesa tones. 600 watts, dual preamps that can be used simultaneous and blended, onboard compression, etc, etc. This thing can really do anything you want it to do. Details here: MESA/Boogie® These can be a little hard to find, (check verb price) and especially so with the foot pedal, which is included. The head only weighs 28.6lbs and isn’t much larger than a Mesa TT800. Two slides for one EQ have broken off. They now act as keys to adjust the EQ on those two slots. It could be fixed, I change the high end rarely and there is a terrible knob on that same channel, so it hasn’t bothered me. New this head was over $2100, my original price $750, price dropped to $699 shipped CONUS. I have a Mesa Box designed for this size head with the foam or an old SKB 3 space plastic rack, well packed and boxed. I love this bass head, I have just been using my Mesa M9 more lately and there is a bass in the classifieds I have been eyeballing.
