I'm looking at getting rid of my multi-FX RP1000 and going back to more conventional pedals. One effect I use a lot is a compressor but I'm a bit stuck on what to look for. I use it on both the clean and dirty channels to liven clean sounds and thicken and sustain my tone on the dirty channel when I can be using quite a bit of gain. I think for the way I use it I'd need a Compressor with a good amount of headroom. Anyway, my research so far indicates that these would all be decent buys:
Seymour Duncan Double Back
Would any of these stand out as a 'best buy' or should any of these be avoided compared to the others?
