The only experiece i have with a compressor pedal is with the MXR Dynacomb. A love, sometimes, and hate, mostly, experience. Never got the total hang of it. Probably my shortcomming. Sometimes i thought wow...this works fantastic...but then with another guitar...yuk...time to try out something else. Than this UAFX device came along for a starkly reduced price. Thought...well, lets try this thing out.....can always return it. But...i'll keep it. It works , in my world, completely different than the Dynacomb, There are no prominent quacky sounds, the sustain is not as prominent an long lasting....but it does something to the sound....lifts it up...gives it a subtle dynamic....helps me to reach 'the edge of breakup' with just my guitar's volume knob. use it for two weeks now. This one stays on my board. Like it very much!
