I have a violinist who has been searching for an octave pedal that would work for her. After doing alot of research I came to the conclusion that this just isn't possible without spending tons of money. But curiosity got the best of me and I built the lowrider anyways. I figured I would keep it didn't work for her. The day I finished it I took it over to try and it worked flawlessly. I was amazed! The oct up is meh... but with a little clean, a little oct down and a little 2 octave down it sounded like a full orchestra! This is by far my favorite build. Maybe i can steal it back to get some pictures. Anyway, Thanks Brian!
