I need help with the following situation. We have a small gig tomorrow night and I am worried about the output I will have. I own 2 combo amps; an Ampeg BA115 and an Acoustic 20 watt 112 combo. I am not sure that the 100 watt BA115 will have enough umph for this gig. I was wondering if it would be advisable to link it up with the Acoustic 112. The Ampeg has an XLR out and I was considering using the XLR out and going into the Acoustic combo via a XLR-1/4" cable. Is this a viable option to increase volume? I know that I sould evnetually just get a better rig but that is not an option right now and am curious if my above idea would help.
