Thanks guys.
Yeah, I have a multi-effects unit; but the sounds are too digital, that’s why I am going analog.
When I tested the two pedals the MXR M-102 Dyna Com sounded better than the Boss CS-3 IMO, but I honestly didn’t have enough time to tweak all the controls of the Boss pedal.
Both pedals are build like tanks and should last for a long time. :D

I came across the Rocktron Big Crush when I started to look for compressors and I liked the price and the features, but I keep hearing people say that it is noisy, and noise is the last thing I need in the signal chain. ;)

Thanks guys your advice is really appreciated.
