PREFACE Neuron is the culmination of years of research and development. We studied the gain circuits of pedals and amps — both tube and solid state — to learn not only how they sound good, but why. We developed new and unique algorithms to test our findings, then refined these algorithms based on what we learned.

INTRODUCTION Neuron achieves a seamless array of incredible amp tones in a compact pedal — from sparkling clean to heavy distortion and everything in between. A multistage, dynamic gain architecture yields unparalleled control over the desired amount of distortion — effortlessly producing harmonic structures that range from subtle to dense and complex.

To Amplifier clean channel input Tip: The small speaker in a practice amp may sound more full-range; therefore, try enabling the Speaker Simulator when running into the clean channel input or effects loop return of a practice amp. MIDI Adapter cables to convert from 2.5mm TRS to 5-pin DIN are included.

CONTROLS Setup Controls These controls are accessed by holding down the Engage footswitch while turning the knob. Speaker Simulator This control turns the internal speaker simulator on/off. LED Color Knob Position Use yellow- full counter- external speaker simulator such as Iconoclast, green clockwise amplifier head &...
PRIMARY CONTROLS Gain The Gain control provides over 60 dB of gain, ranging from clean to heavy distortion. This control is level-compensated: increasing the gain increases distortion but only slightly affects the level. Comp The single-knob compressor ranges from none to heavy compression. Increasing this control simultaneously decreases the threshold and increases the ratio and level parameters of the compressor.

ALTERNATE CONTROLS These controls are accessed by holding down the Engage footswitch while turning the knob. Gate The Gate control adjusts the noise reduction threshold. Fully counter-clockwise is off. Set the Noise Gate as follows: Press and hold the Engage switch. Start with the Gate knob fully counter-clockwise.
USING PRESETS Manual Mode: The Preset LED is off. All settings will be reflected by the knob positions. All alternate controls will retain the values last set when in Manual Mode. Preset Mode: The Preset LED is on. All Primary and Alternate controls are recalled from a stored preset.
