Mayonaise Mk 2(released late 2010)(37 made – Marc says “37 Mayonaise MkII’s were made. Serial number beginning with zero, 2 made with serial #22 (yep), and last one was #35.”)(The Mayonaise MkII was in a small box, with a mids switch, plain steel, and black lettering)

Marc Says (via TGP):?

"The (Mayonaise) MkII used the newer transistors too, but at higher gains (which the original triangle knobs had in them) and then a slightly larger emitter resistor to tame them down a bit; but all capacitors were of the same type and values as the original triangle knob."
