I have an Ampeg BA115 that I absolutely love except for one thing, it doesn't offer an output for an extension cabinet. I have an Eden 2x10 that I would like to power off the Ampeg but have to use a separate head. Is there anyway to run another cab off of the BA115 either by some sort of mod or using the XLR output? Could you run the XLR into some sort of small power amp then to a cab? Of course then you aren't doing much different than using a separate head for the cabinet. I haven't seen anything on the Ampeg site as far as combo amps that offer an output for second cabinets. I know the SWR Black Beauty does and probably some others but I love my Ampeg. Thanks in advance for any suggestions.
