Mojo Hand Fx Speakeasy Boost / Preamp

 They Say:

Based on the revered EP-3 circuit, the Speakeasy one-ups the competition by giving you more shaping ability and tonal range. The separate gain and volume controls essentially double the preamp’s usability while the addition of a full range tone knob and 3-way "thickness" switch allows you to tailor the Speakeasy’s tone to your needs.

Features:
-Gain, Tone, and Volume controls.
-3 way "thickness" toggle for use at higher gain settings (up: more punch, center: neutral, down: more low end)
-Excellent choice for bass! Solid low end response all the way down below 30hz. 
-True bypass

Power:
-Standard center negative 9V DC supply, or 9V battery (neither included)
-Current draw: ~3mA
