This is the CP-12 Pure Sky Overdrive from Caline.

One of their workhorse units that simply does what it is supposed to and all at a price within reach of any player.

Caline Cp-12 Pure Sky Overdrive Boost:

This pedal provides a very pristine clean to a very smooth, compressed, overdriven sound., Inspired by the Timmy Overdrive's sonic output, the Pure Sky provides high pure and clean overdrive response which sustains the original timbre from the amplifier. Volume and Gain controls can take you from Clean to Hard Rock and everything in between.

Features: True Bypass design minimizes any tone loss.

Full metal case, Sturdy stomp switch.

Can be connected to a negative center 9-Volt power supply. (not included)

Grab one before they go....
