I have tried to use the external amp out jack on my T50c with pretty lackluster results. I have my T50c on top of a T50 1x12 cab, running it at 8 ohms (two 16 ohm speakers). I then run my line out to an Alpha Slave powering a Model T 4x12 cabinet. If I run just the T50c and a cab, it is LOUD. When I plug anything into the line out, it KILLS the power of the T50c.
Am I doing something wrong that I am just missing? My Betas have always functioned the same, volume-wise, when I used the line out. This is a first to me, and I do not see why using the line out on an amp would cause it to lose power or volume.
