A world of experimentation!
The OFF1 pedal features 3 analog stand alone circuits in series: Octave (sub1 & sub2), Fuzz (with switchable octave up effect) and Ladder Filter.
Octave and Fuzz can be used individually for a more canonical approach of the two effects, while from their combination brings more experimental results.
The first effect in the internal signal chain is the Octave and then in series come the Fuzz and the ladder Filter.
By applying the Fuzz’s high octave effect and Filter on the low octaves you get out of the ordinary sounds and synth-style effects.
Lets take a look at each circuit.
Octave : The Octave circuit belongs to the family of the old monophonic octaves and can add the two octaves below the original note. Each octave has a separate volume control and plays back with outstanding clarity, thanks to the very precise and fast-tracking circuit, which allows even bridge pickups to be used without difficulty.
Fuzz : Fuzz has an edgy and grumpy character; it doesn't like being compared to other Fuzz tones. It’s capable of producing a wide range of tones from every fuzz era with careful tweaking of Gain, Tone and Mid frequencies controls. From thin and harmonic, to thick and growling. A pair of diodes is also used in the circuit to achieve the octave doubling effect reminiscent of the old octave up tones of the late 60's and early 70's. The high octave can be activated manually via the toggle switch or via the left footswitch when the pedal is in Mode 2.
Filter : The filter circuit belongs to the family of the legendary synths ladder filters and comes with the inevitable Cutoff and Resonance controls. You can crank the resonance and sweep the cutoff to hear those characteristic and wonderful harmonic peaks. The Cutoff control can also be controlled via an expression pedal (or CV) using the dedicated rear jack. The filter works combined with the Fuzz when the filter toggle switch is positioned downwards.
