I've don't have experience in bi-amping, so I'm asking the pros here at TB. I have a Crate Bt-350 head and a Hartke 2000 head I'm fooling around with. I was thinking of running the Crate as the bass amp through an Ashdown 1x15 cab and bi-amp the Hartke as the high amp through a pair of 2x10 cabs. First off, is the Hartke bi-ampable? Would I run the high out of the Crate into the front input of the Hartke or to the effects return input?
