[The Late Great Libido]

I have a Sonic Stomp last in line on my pedalboard and I think it does wonders for my tone. It basically cleans up the sound - clearer highs, less mud in the lows. Its one of 3 pedals that I leave on all the time and one of those pedals you forget is on - but when you turn it off you miss it. I have no experience with the rack mounted units...
