July 9, 2025 · 2 sources

The Diamond Pedals F-Octave returns as a 2025 edition, reported on July 9, 2025. The original version had three knobs and the Octave toggle switch, while the new edition adds a Low Pass Filter control, with the original Level, Fuzz and Tone controls retained¹. Delicious Audio describes the pedal as having "reclaimed its spot in the Canadian brand's lineup"².

The pedal is an analog silicon fuzz and octave effects pedal¹. An OCT toggle switch selects between two modes: up gives fuzz only, down engages the upper octave¹. Delicious Audio describes the Octave mode as engaging "upper-register harmonics for synth-like textures and cutting leads," and the Pure Fuzz mode as delivering "warm, mid-heavy compression"².

The enclosure is purple with a different gold yellow accent color from the original¹. The pedal has top-mounted jacks, soft touch relay switching and true bypass, and is hand-made in Montreal, Canada¹. It runs on a 9-18 V DC power supply (center negative, roughly 20 mA current draw)¹.

The F-Octave is priced at $2295 and is listed on the Diamond Pedals webstore, with availability at dealers described as imminent¹. Delicious Audio traces the design to 2017, when it was first introduced as a homage to the Foxx Tone Machine².

Delicious Audio reports the pedal works on both guitar and bass, and that rolling back the guitar's volume reveals sputtery breakup while maxing it produces sustained notes². It sits among octave and pitch pedals from Diamond.
