I have been building a pedal board to make more use of the effects I have aquired over the years. Many of the distortion type effects for guitars cut off the lowend and take all the 'bass' out of my bass. I have been making a second loop out of a dry out from a stereo pedal, and sending the bass cutting pedals to the second chanel of my amp. That way the most of the bottom and original tone is preserved by the first channel, and I can still get a good distortion sound with low end. I run the second chanel a little lower and between them both adjust the volume so its about the same as I would run on chanel one alone. chanel 2, I boost the highs a tad (1:30-2) and cut the lows (11:00). Is it 'bad' for the amp to use both channels? It doesn't seem any noisier, and I can get a little fatter of a clean tone with both channels. Its an early SVT head. I play passive basses, a Jazz and a Ric 4003. If its bad for the head, I will invest in a line selector or blending looper to deal with the bass cutting noise pedals.
