Booster

The Blues Power is a true transparent overdrive. It produces a full range, amp-like tone with responsive bass and treble controls, wide range drive control, internal switches for middle frequency adjustments, and a volume control with enough output to drive even the most stubborn tube amp. This is a mighty overdrive indeed.

The goal in creating the ZIO Analog Front End + Boost was simple yet ambitious: "Make Everything Sound Better!" ZIO is an all-analog preamp/boost pedal that includes a choice of four distinct preamp circuits, each with up to +20dB of additional output boost. ZIO is Source Audio's first all-analog effects pedal and designed in collaboration with Christopher Venter, the owner and sole engineer at SHOE Pedals.

Dual Overdrive/Boost and Distortion. TS808 meets Bluesbreaker....

It is a unique two channel combination of clean, transparent preamp / booster and rich overdrive / distortion that can work independently.
