Designed to recreate the overdrive of a mid 70's ~ early 80's Marshall!

THE Marshall sound.

A full sound with natural compression without any high end loss.

The Karen replicated the fat, full overdrive tone of the mid 70's to early 80's era Marshalls such as the 4 input JMP and the 2 input JCMs.

It's an overdrive with thick saturation and a pleasant natural compression.
