MK Ultra

The Yellowcake MK Ultra is a pedal that combines elements from the traditional octave up circuit and integrates them with a fixed wah circuit using the 'MIND' knob. The 'CONTROL' knob allows users to modify the frequency of the fixed wah. This pedal is designed to be versatile with just these two knobs, offering a wide range of possibilities. It is meant to be paired with a fuzz pedal of the user's preference, but it also lends itself to plenty of experimentation with other types of distortion.

Technical Specifications:
- Mind: Blends the octave up signal into the fixed wah circuit.
- Control: Adjusts the frequency of the fixed wah.
- Power: 2.1mm negative center 9vdc adapter.

The MK Ultra pedal is designed for guitarists and musicians looking to explore unique harmonic effects and experiment with blending octave and fixed wah tones in their music.
