The OFF1 pedal features 3 analog stand alone circuits in series: Octave (sub1 & sub2) + Fuzz (with switchable octave up effect) + Ladder Filter.
Octave and Fuzz can be used individually for a more canonical approach of the two effects, while from their combination more experimental results can be obtained. 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 are projected towards moods close to the world of synths.
