Hi folks, I am buying another 2x10 used Ampeg Cab primarily as a practice cab to be left at home and/or left at one of my drummer's places. I just hate lugging cabs around 3x a week. Anyways, I have a few large outdoor gigs coming up and I would be interested in understanding if there is any way to hook up 3 cabs (two Ampeg 2x10 and one Ampeg 1x15) to my Ampeg B2RE head. My current setup is as follows: - Currently one 2x10 and one 1x15 cab is attached to the 2 speaker ports on my B2RE. - I run a Bass PodXT directly into the Effects Return on my B2RE. - I also run a few effect pedals - Boss Chorus Ensemble (which has a stereo option). MXR 10 band EQ and MXR auto Q. A 2 cab config is perfect for indoor gigs, but it would be great to be able to use the 3 cabs together provided I didn't need to buy anything else. Thanks!
