I have a Carvin R600 head with a 2x10 and a 1x15 cab. Anyone know if it's possible to take a Carvin amp in bi-amp mode and run a distorted signal to the high frequency cab and a clean signal to the low cab? I was watching that movie on Spectors web page of Quintin Berry and it sounds like he is running some sort of split signal thing. One distorted and one clean. Sounds awesome!!!
