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:

Based on the tone control of the Diezel VH4, this will make tweakholics, and high fans fall in love as equal!

Introduction

At first, it might look pretty similar to the Amp Tone stack + Gain recovery, as the first section looks pretty similar. Both start with the 3 band Amp tone stack and the Gain recovery stage. However, the first difference is the Presence control, located after the gain recovery stage and bounded with the Deep Control. This design also includes the possibility of having two simultaneous outputs as the Active EQ, featuring the same type of power output and tame output.

Important! You should be able to read schematics to fully understand how and where to add these EQs in the best possible way.
