The comp is just as it's name implies, clean and quiet, with crystal clear compression that transmits the sound of the bass through it. It's very similar to my Smoothie, so I don't need it. Mint condition save for industrial strength Velcro on the bottom. $100 shipped The OC2 works perfectly, and has a square wave switch added to each octave to make it more synthy sounding. $75 shipped. Treades: Not much I need, though I would add cash for a VTBass DI, Diamond Bass Comp, and maybe a couple other things. PayPal is fine.
