Burriss Boostier II Pedal"The Boostier II is a fully adjustable clean gain preamp. It can be used as a unity gain buffer at the front of your pedal line, or as a "make up" preamp to equal the output levels between single coil and humbucking pickups. It can also be used to boost the signal at the end of a long pedal chain. The most common use is as a lead boost which allows you to stand out in the mix like you are riding your own slider on the mixing board."
