i've had my 21012 for a few months now, and i'm lovin it. this morning at the shop i couldn't resist trying something. i plugged it in to my buddie's guitar head and played it for a minute or two. i didn't push it or anything but i did notice that it sounded pretty damn good. my question is. since i play guitar also, have you ever had anyone use your cabs for guitar, and could i damage the cab (specificly the tweeter and crossover) but using it as a guitar cab.(high gain distortion and such)? i was careful and didn't push the cab too hard when i tried it, but i would love to hear what it would sound like cranked up. however i will never do it again if there is a chance i could blow something cause that cab is my holy grail for bass. i just love the idea that it could satisfy my guitar needs as well. btw for all you out there that go both ways(guitar and bass) i was using a randall pro tube 100 watter with a metalzone and a voodoo labs analog chorus (amazing pedal) the schroeder sounded like it would excell at metalish and clean sounds. (never tried my overdrive pedal though) very tight and controlled with lots of clarity. didn't eq it at all just left the settings like my buddy keeps them, but it sounded a little scooped with guitar. not bad though. i just couldn't resist bustin' out a little cowboys from hell and old metallica riffs that i haven't played in years.
