Hi i'm looking to buy a compressor to add to my pedalboard, just wondering if i need one specially designed for bass or if something like the boss cs3 would be just as good?

Any particular pedals you'd recommend?

Get the Trace Elliot Dual-Band, or a similar dual-band compressor if possible. I can't put mine down...

But the EHX Black Finger/White Finger and the Demeter Compulator sound gnarly also. Pretty much every unit on the market sounds different to me; try out a few of the mid-range ones. IMO the bass-centric pedals are pretty much necessary.
