Six gain stages preamp with a lot of attenuation and select filtering between each stage to get the desired frequency and phase response characteristics of the original Peavey EVH 5150 head preamp section. Features a 3 band tone stack with an additional gain recovery stage.

Even if this PCB is pedal-friendly, this beast shines the best as a Preamp on the FX loop due to the immense amount of output.

Introduction

Wolfgang is based on the signature Amp one of the most influencing guitar players of all time and most likely the reason for many of you to start playing guitar! I mean, you read the name and have the riffs in your head, aren’t you? But some of you may still not be 100% sure who we are talking about? Okay, I stop to rave about this guitar genius with the black and white strips running all over his red axes and come back to the topic.

For this pedal, we went back to the roots and stick with the Tube preamp’s original Schematic preamp, modeling it to make a useful Distortion for the old fans, the modern players, and most importantly, for the DIY builders.

The board allows using either T0-92 or SMD Footprint. We also added a 3-Band EQ in the newest vertions to tame this angry beast for your needs and pressed all this insane amount of Gain and Volume this build offers in a 1590BB enclosure. This is not a beginner project but a rewarding one.

This beast has an insanely loud output, so remember, you can achieve great results with this pedal in your board but is on the FX loops where this beast shines.
