EarthQuaker Devices Rainbow Machine

 Chris "SPIN Doctor" Stelloh did it again! Amazing work with this box of fairy dust and chaos. The layout is verified and good to go!

  1. Anders, I must thank you for challenging me to draw this. It was the push I needed. Also - I most likely would not have been able to complete this were it not for the clear and concise schematic that Madbean put up for their "Rainbow Puker" project. The 'dry kill' switch addition was Brian's idea and, should any of you want to fit this circuit into a 125b-sized box, head over to Madbean's shop and buy a PCB!!!

  2. I bought a rainbow machine during covid and just can't connect with the thing. Fun I guess but useless. Maybe I'll mod it with the dry kill.

    1. From a design standpoint, I am blown away by it. So much cool stuff that EQD got out of the FV-1 without needing an additional algorithm chip to tell the processor what to do. But as far as the actual sounds that come out of this pedal? I admire what Nick Reinhart is able to do with it, but I doubt that my build of it will have a home on my board... if you do attempt to mod yours (I've never looked inside one of these so I don't know if they are SMD or not) check out Madbean"s schematic first - you will see where the dry kill switch is placed between the output of the 1st TL072 op amp channel and the input of the other one.

    2. Pitch shifters don’t have a rich history in music for a that reason?

    3. Sure. I mean, who's ever heard of ANY important, innovative, or influential guitarists using a digitech whammy? ;)
