Hey guys, I hope I can get some help. I recently got a randall rh200sc head and matching cab. The head can do mono or stereo. I have it hooked up mono with one speaker cable and its just not very loud at all. My other guitarist has a marshall vs100 which is obviously less watts but is quite a bit louder than my randall. What could be causing this? Its really a problem because im getting drowned out in the mix.... Since this amp has a stereo setting, is it only running at half watts (100) and using 1 power amp (dont stereo amps have 2?) It seems like hooking it up mono would use both power amps but I may be wrong.. I dont have another speaker cable but I can buy one if you guys think hooking it up stereo will solve the problem. Ive read that these things get LOUD but mine is barely loud enough to contend with the marshall at full volume. Also, if this isnt the problem, what else could it be?
