The Fredric Effects Scrambled Brainz is an improved Ampeg Scrambler clone. For the MkII version, we've added a boost circuit and volume control, so you no longer have to make do with the unity gain of the original circuit or straight clones.

They're handmade in North London, UK, using high quality parts and circuit boards we've designed ourselves and cost £85.
