Heads up Builders widely report inconsistent quality from PCB Guitar Mania boards, and whether a given board works is a gamble. Read recent forum reports before ordering.

From the vendor

Project overview

The Freeman Supreme is our own custom model inspired by both Friedman BE-OD and Friedman’s Dirty Shirley! This circuit has been designed to have the ultimate classic fuzz tone with a big low end, a biting top end without being too harsh.

Introduction

The perfect fuzz! According to the people from EQD at Akron, Ohio. Inspired on the classic fuzz face featuring an input buffer and a pickup emulator (transformer).

For this project, we have included an internal volume trimpot as well as an additional Bias to have more control on the main Bias control outside the box.

Featuring:

• Dual-channel with independent Gain and Volume control

• Two foot-switches, for Channel select and Bypass

• Specially design dual 3pdt board to keep the wiring neat and tidy!

• Three-band EQ controls Bass, Mids, and Treble.

• Tight and presence control to have a precise control of your tone!

• Character Toggle, this switch allows you to select in between two different gain presets of your choice! You can configure it on your own way thanks to a couple of internal trim-pots!
