I'll go straight to the point: are you looking for the most transparent compressor? Do you need a clean boost, or a more "compact" sound for your guitar? Do you like to play funk, country, fingerstyle and you desire evened notes along your playing? This is the right pedal for you.
Don't get fooled: Only two knobs doesn't mean less capabilities; inside the pedal there are two controls that allow you to turn up or down the Attack and the Input Signal level, just as the 4 knob edition! The stock settings are very sweet, and I didn't need to turn any of these controls, but now you know that this 2 knob version includes everything you need.
Sometimes I use this pedal as a clean boost; just turn down the Sustain knob to zero, and increase the Level amount. Wonderful, isn't it?
Finally, we all know Keleey quality. So, don't trust me: trust in years of experience and hand-made fine work. I couldn't be happier.
This pedal adds UMPH!!! I utilize the 2 knob version simply because I'm unafraid of opening up my pedals and making adjustments to internal pots, and I didn't see the point in paying extra for more clutter to mess with up top. I tend to use guitars with lots of volume and bite, mostly humbuckers and mostly larger body guitars. I also have the interesting position of sharing my pedalboard with my bassist whom I switch instruments with. For his play-style and taste he picks up much thinner, slinkier, and lighter sounding single coil teles or strats. I've encouraged him to utilize this compressor to make up the HUGE difference in the volume and tone between these types of pickups and guitars. This compressor gets the job done and adds ridiculous amounts of sustain. For my personal tastes I only really engage it during solos if I want a tone more boost, however it has become an always on pedal whenever anything but my HH guitars goes into the rig.
