Just built myself a 2 in 1 with a Marshall Supa Fuzz (mkI version) and a Dizzy Tone. This is the 1st mkI I've truly gotten biased just right. I had to use some incredibly leaky Japanese trannies to nail it. I can build Dizzys and Buzzarounds and mkIII's all day but the mkI is a bitch. It sounds glorious though and shockingly they sound pretty rad together.
