MetalHead Electronics – Original Marshall Amp Modifications


Original MetalHead Electronics Marshall amplifier modifications by Elan Memran

DINO CAZARES / FEAR FACTORY TONE

The original MetalHead Marshall modification by Elan Memran, featuring the custom high-gain modification and built-in noise gate that helped define Dino Cazares’ signature guitar tone.

I’m Elan Memran, founder of MetalHead Electronics. I developed the original Marshall amp mods in North Hollywood, California, including the high-gain modification and custom noise gate installed in Dino Cazares’ Marshall JCM800 2203.

The original MetalHead Electronics Marshall modifications are back. Every modification is personally installed and tested by me. Customers throughout the United States can arrange to ship their amplifiers for modification.

DISCOVER THE ORIGINAL METALHEAD MARSHALL MODIFICATION

The Original MetalHead High Gain Marshall Modification

This is my original MetalHead high-gain modification from the North Hollywood days, associated with Dino Cazares and the early Fear Factory sound.

I add an extra tube and my original MetalHead high-gain circuit to your compatible Marshall amplifier, along with two additional gain controls.

The modification produces more gain, sustain, and control while keeping the character of your amplifier.

Combined with my original MetalHead noise gate modification, this is the setup I developed for Dino Cazares’ Marshall JCM800. The noise gate is also available as a separate modification.
