TREBLE: Controls the amount of high frequencies in the signal. Set below noon for a darker tone, and above noon for a brighter tone. At higher settings, it boosts upper mids as well.

VOLUME: Controls the overall output volume of the pedal. Even at low Gain settings, provides plenty of output to boost clean sounds loudly. May not need much adjustment with higher gain settings, especially in Stoner mode.

STONES/STONER TOGGLE: Stones Mode emulates the authentic response of a big Ampeg tube amp and delivers classic, refined tones with a slight emphasis on lower mids, akin to the iconic Ampeg sound. Ideal for achieving clean to slightly overdriven tones. Stoner Mode transforms the pedal into a
high-gain distortion powerhouse. Designed for players seeking ripping distortion tones and the ability to produce huge fuzz sounds.

BASS: Adjusts the amount of low frequencies in the signal. Turned down from noon for a tighter response, and up from noon for a bass-heavy sound. At maximum, it provides a huge boost in low-end frequencies, suitable for fuzz settings in Stoner mode.

GAIN: Determines the amount of overdrive or distortion in the signal. At lower settings, produces a clean and bright response. From 10:00 to noon, yields an edge-of-breakup tone sensitive to pick attack. Between noon and 2:00, hits the overdrive sweet spot akin to most tube amps. Beyond 2:00, increases crunch and saturation, adding more distortion to the signal.
