Hey guys, I have a gig tonight and am cab-less. I have an ampeg v4b and was going to borrow both my friend's 4x10s for tonight. However if I remember correctly the v4b only has one speaker output. If i wanted to use both cabs could I slave my V4b to his SVT-CL and also overcome the issue of the V4B not having enough volume in a big room? If so would I plug a cab into each head and just use the slave out of the V4 and into the SVT? If I did this would there be sound coming out of both cabinets? Sorry if this is a stupid question, just want to make sure I do this right and don't blow a tranny. Thanks in advance!
