MetalHead Famous Gain Modification:
This is the high-gain modification I was doing at MetalHead Electronics. An extra tube and the original MetalHead high-gain circuit are added to your Marshall, along with two additional gain controls. More gain, sustain and control while keeping the character of the amp.
