Picked up this at L+M last week and love the compressor side of it. Still working on the gain side and have not really had a chance to open it up. Saturday gig was low volume so could not give it a good workout but i must say the compressor side of it is great. Been using a Boss CS2 for about 5 years and the Keeley offers superior tone. Highly recommend trying one out if you are looking for a comp gain pedal all in one.
