I just got a nice deal on a 400BH mark IV. I love the tone, real raw and gritty when the gain is set pretty high hehe but i feel like its lacking in power, mainly because im used to my other amp, Carvin b1500 I was wondering if it would be possible to hook the B1500 up to the power amp jack in the peavey using the B1500 effects loop. or would both amps have to have a speaker load? and not just the B1500? because i only have one cab... Im basically wondering if i can use the B1500 as a slave of sorts.
