Nice Henge Burnsy! What speakers do you run in those guitar cabs, guitar or bass speakers?
Thanks Max! All the 12" speakers are stock guitar speakers. Unbranded ones in the vertical Sovtek cab, I'm led to believe they are actually Eminence, whichever model is their Greenback clone. The Marshall has it's original Celestion G12-65 speakers. Yes, I am ignoring any conventional wisdom that says I'll damage guitar speakers by playing bass through them. I haven't had problems. My feeling is that the cascaded-gain basic Marshally preamp design trims the dangerous bass, so the remaining signal is pretty benign.
