Hey TBers Looking for advice on using compressors on a split signal chain going into one amp. Not technically bi-'amping', but dealing with compression on separate signals. I never used compression much, let alone on a complex signal chain. My signal chain is clean bass into a OBNE Signal Blender which splits the signal into three separate effect loops. Lets call them Clean, Dirt and Synth. These three loops can be run in parallel or any mix of the three. Usually I keep Clean and Distorted on always. Clean 'loop' is clean. Keeps the low end untouched. Dirt loop goes through two dirt boxes, sometimes with ambient reverb and a chorus/vibrato. Little low end. Synth loop goes through a synth pedal (duh). Alternately a fuzz. Little low end. So three very different signals going on. The three loops are then combined and run through a wah, a looper and a delay into a single amp. The amp (Ampeg PF-500) has an onboard single-knob compressor running at about 8 o'clock. Never gave much thought to it. Would a single compressor before the amp squish the 'wrong' frequencies? Say I run Clean and Dirt with ambient reverb. The compressor would kick in when the reverb hits the threshold, and squish the whole signal, including the Clean, no? Running a separate compressor for each channel would mitigate this, but that seems a tad excessive, not to mention expensive. The Synth loop is not very dynamic to begin with, so maybe a compressor would be of little use? At the moment I am looking at running separate compressors on the Clean and Dirt loops. Light compression on the Clean, and heavier compression on the Dirt. Feel free to unload your compression wisdom on me. Do you compress before or after reverb? What about delay? Does your wah go into the compressor or after?
