I just picked up a Yorkville XC410 for $250 and a Fender BXR Dual 400 for $100 (steal! ) and since the BXR is a bi-amp head, I'm wondering if the Yorkville is bi-ampable. Quite honestly I didn't realize that the BXR didn't bridge the amps until I just read about it online, though it doesn't really matter because it drives that cab pretty damn well. Also, this is my first cab/head (only had combos in the past) and I'm wondering if the dual inputs on the back of the Yorkville are both inputs (thus the bi-amp question) or if that's for setting it up in series with another cab. Thx! PS - did I get a good deal on these?
