If you turn the compressor level right down you can engage the boost with no audible compression... Great optical compressor probably the nicest I've owned but hate the standard strymon box. Needlessly large for what is inside in this instance... As far as the boost goes, there are 3 presets which can have their frequency shifted slightly via an internal dip switch but I found for me personally I could never quite get the frequency to a sweet spot for my rig. Obviously this may not be the case with other peoples set ups..
