In stock form, the Blue Box suffers from an anemic volume - even when turned all the way up. I add a small boost circuit in the battery compartment - complete with an adjustable pot. Now, you'll have plenty of volume on tap without sacrificing the unique fuzzed out tone this pedal is known for. Additionally, I add bright LED's and upgraded knobs in your choice of color.
