No longer being built and primarily for the Japanese market. Tonegod mentioned this in the restrictions, which is strange because is not mentioned anywhere on the forum or even on thegearpage.MFOB
This unit is known by two names:
Modified Frequency Overdrive Box, and
Monkeys Fly Out Butt.
The MFOB is a two-stage overdrive unit
that produces a tube-like square wave
when cranked. Controls are Volume, Gain, and
Universal Gain. Used by THE BLACK CROWES
and Page Hamilton of HELMET.
All this sounds very promising. Why did it go out of production?
