it's a little tone-shaper/preamp. it doesn't provide any boost (only cut), but it changes your sound, making it smooth and rich like R&B. i've found it to be extremely useful after the overdrives in my VFB2 blended loop. it makes these richer and more bassy.what is a submarine?
also, if you want to go blind, stare at the LED for a minute or so.
