Hiya, I've been fiddling around with a Behringer MDX2600 rack compressor for a week or so now. So far I've learned I have LOTS more to learn about compression, and that its a neat tool. I'm running a Tech21 Landmark 300 head with a single Bag End S15-D cab. I'm looking to add some punch and tighten up the bottom end a bit. I just do basement jams and such, no gigs or anything so thats why I went with the cheap Behringer. I saw in the local Craglist today there is a used DBX166 for $200 cdn. New they go for almost $350 here, my Behringer was cheap, only $120. Is the DBX going to be 3X as good as the Behringer? I can return the Behringer for store credit, but I'd only do that if the DBX is a far superior unit. Can anyone help a noob! Thanks!
