I'm not sure, but I would think not. It's a pretty small amp, meant for solo practice. They normally don't support an ext spkr.
Yeah, you're right. I got to checking on the specs and realized that I'm not gonna be able to hook up an extension cab or speaker to it. I recently bought one of these, and while I do really like the tones I'm getting out of this thing at practice level volumes, it wasn't getting loud enough when I had a couple buds over to jam a little. Even without drums, it was failing to get any real volume going without distorting. I guess 100 watts in a SS bass amp combo is still a practice amp...
