GOBLET

optocoupler filther

GOBLET is an analog filter and distortion unit with some added quirks and extra controls.

why
• To make stuff sound filthy.
• To shape the output of an oscillator.
• To live interact with the sound during a performance.
• To soft sweep the cutoff thanks to the optocouplers logarithmic response.

with
• Simple waves – make them unrecognizable.
• Complex waves – shape them into something new.
• Percussions – crank the resonance and give an acid twist to a beat.
• No input – play with the feedback and the touch controls.

features
• Unique analog two pole circuit with custom optocouplers fed directly in the feedback path.
• Two step controls and individual CV inputs on frequency and resonance for precise sound sculpting.
• Dedicated potentiometer for the total amount of feedback.
• A performance-oriented momentary switch for extra distortion.
• Two expressive touch points to make your body interact with the circuit.
• Rhythmically oriented accent CV input.
• Two outputs – a smoother LP and an aggressive notch.
• Works with audio and CV sources.
• Single board design – extremely skiff friendly.
• “Whatever” power connector a.k.a. don’t mind the polarity.
