The Ladder to the Moon is a guitar synthesizer with a tracking oscillator that is tunable to any harmonic, with over an octave of tuning range. It also has a saw waveshape, two types of phaser modulation and vibrato.

This pedal is CMOS based and is similar in features to the C19 Databus Drive, but in a smaller more DIY friendly 1590BB format. Keep in mind that this pedal is monophonic, so play single notes to get good tracking.

It is named after the art by Georgia o'keeffe.
