Roger Mayer Octavia

Roger Mayer is one of the most influential effects makers of all time. Responsible for many great players fuzz tones, he's probably most famous for tweaking (or just rebuilding) Jimi Hendrix's Fuzz Faces. He also has his own line of pedals and this is his take on the classic Octavia (octave up) effect. This one doesn't use a transformer like the Tycobrahe Octavia, so it's a little easier to build (at least you don't have to order a transformer...). This layout follows Roger's original 2-knob Octavia,  housed in a spaceship looking enclosure.

    1. I think there's a mod to lift the diodes, but that just turns the fuzz on/off, not the octave. Don't think there's a octave on/off mod. But if you come up with on, by all means let us know!

    2. the reason I'm wondering is this FFm6 ( https://www.youtube.com/watch?v=AezErLNaqjI ) that is described to be an octavia circuit without an octave up part.

    3. Ah, that's based of the Tycobrahe Octavia.On that effect you just have to install a SPST switch on one of the diodes coming off the transformer.

  3. What are the dimensions of this board? Trying to print in it's actual size.
    Thanks for the PCB! Saved me from buying the transformer (Which was impossible to find anyway.)

    1. Scaled pdfs of all layouts can be found in the Transfer Image Library tab at the top of the page.
