I play mostly in church but do have some use for a smooth overdrive in my second PA channel. I'd like to improve upon the OD-3 and wondered if the Small Fry BU might be a good choice where you primarily want a nice smooth crunch or OD when playing rhythm.
The Liverpool supposedly emulates an AC-30 and will overdrive but it's normally set clean. At best I might be able to stomp on one pedal between songs, other than that I have to keep the "train" rolling.
