The Surgeon Delay



(2 customer reviews)


What if the gain section from a opamp big muff and the eq section from a metal zone had a baby… That weirdly awesome combination is the Ghoul fuzz and its ready to melt your brainz……

Out of stock



How this came to be

I am not a big fan of the boss metalzone but like everything Boss does there is some serious genius in it and with the metal zone, for me, its the EQ section!
A 3 band active eq with a parametric mid control gives you such great control for a gain circuit. You can actively boost or cut the highs, mids and lows while also being able to adjust the freq range that the mid control affects! This lets you create really unique eq/gain combinations.

Since I wasn’t a fan of the gain section of the MZ I instead switched it out with the gain section from a vintage Opamp big muff giving you vintage inspired fuzz perfect to bring your tone to life.

This is one unique monster, and one bite will keep you hooked for life.



Ouput – This controls your overall volume. Its pretty straight forward

Freq – This lets you sweep through the parametric freq of the mid control. Think of a wah sweeping through freq except this lets you just pick a certain freq range to adjust and stay there

Gain – This adjusts how much fuzz you get

High – Actively boost or cut your High frequencies

Mids – Actively boost or cut your Mid frequencies

lows – Actively boost or cut your low frequencies
