I personally imported this from overseas. It's a handmade noise machine from the UK. Features: Unpredictable, interacting modulation oscillators in 2 banks of 3. Controls for each bank: Frequency 1 Frequency 2 / Rhythm Speed Frequency 3 Tone Volume The center knob can be a bend control or pitch control depending on the settings. Using this can starve the circuit of power, creating modem-like noises. The banks can be used independently using two jacks, or linked using only the right-side jack (note that the volume is not independent when linked). Red effector with white knobs. - Color: Red - Number of knobs: [Not specified] - Number of terminals: 3 - Knob color: White Thank you for looking. This is custom-made equipment. It's almost unused and in good condition. Please refer to the site: https://share.google/NCAyvqH62QzjdzOQw
