I've had an ongoing love affair with compression for a while and frequently stack two comps when playing guitar. With bass though it didn't seem such a good idea; so many comps make the bass dull and take away the natural harmonics and delicate fingering tones. Recently though I've tried stacking a couple and came across a duo that work really well - The Maxon Tube Comp is a wonderful comp for bass, it doesn't remove any low end, in fact it enhances and boosts the low end. I tried putting a variety of comps in front of it but the one that excells is another Maxon, the CP9Pro+. Stacking the two together (they both are VCO types) gives the attack a kick drum feel - a real percussive thud. The trick seems to be to set the first comp's output high, so that it hits the second hard with the attack set fast.
Anyone using two compressors with bass, if so which ones?
