Folks, I can't seem to find a definitive answer in this forum, so I will ask.... I am planning to run a Mesa all tube D-180 and a Hiwatt DR-103 into a single 410 Sadowsky cab. Reason? One amp for dirty and one for cleans. My questions: 1. Can I have 2 4ohm amp heads plugged into a single 4ohm cabinet at the same time? Physically, the answer is yes, I know. I am more concerned with playing thru one amp with the other amp ON STANDBY with both plugged into the same cab. 2. Can I have the 2 heads plugged into the cabinet with one being used and the other completely off but plugged in? 3. Is there a better way to do this? Note: I will be playing the Mesa for 3 entire sets and the Hiwatt for 1 set. I will not be switching amps during or between songs. Hit me with some TB amp wisdom!
