Ok so I have a MTS Half stack that I play with.I have been trying for a couple years to add to my sound so occasionally I will get another head and cab and try to run both of them. My problem is that when I slave out to the input jacks of other amps, they tend to blow up.Am I doing something wrong here? I run a guitar chord of good quality from my slave out on the randall to the input section on the front of these other amps. And usually within minutes they are blown. So far its been a meas boogie mark IV, a crate blue voodoo, a Laney,and last night a brand new Marshall 50 watt tube head.
