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.
