In my neverending search for tone, I whined to my tech, "My Ampeg B-15N sounds better than any amp I've ever tried, but it's only 30 watts. My Carvin BX1200 has huge power, but it's transparent and dry sounding." Tech: I'll build you a magic box. It will have an input and and an output and a 'dummy load' inside to fool the Ampeg and keep it from blowing up. A line level signal will come from the output, which you will connect to the input of your Carvin. Then you will have the B-15N for a front end and all the power you want with the Ampeg tone and sag." Some other wags are saying this is dangerous and still liable to damage the Ampeg. I love the feel and tone of a tube amp, but don't want to carry a heavy tube amp around, that's how this all got started. Comments?
