Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Free The Tone IF-1D Iron Forest is a high-gain distortion pedal from Tokyo builder Free The Tone, voiced toward modern hard rock and metal rather than vintage grit. Four controls -- Level, Gain, Bass and Treble -- set a tight, focused distortion with a bright top end and a sharp, percussive pick attack that keeps fast riffing articulate instead of smearing. Gain runs from thick rhythm crunch up to saturated, sustaining lead tones, and the two-band EQ lets players scoop or thicken the midrange to sit against a dense mix. The IF-1D uses Free The Tone's HTS (Holistic Tonal Solution) buffer circuit, which preserves high-frequency detail and low-end tightness through long cable runs and complex pedalboards. It suits players wanting an aggressive, articulate distortion with plenty of sustain and a defined, cutting character.
The Warm Audio Dirty Boy Jr. Fuzz is built around the original Dirty Boy Afro Fuzz circuit, part of a three-pedal Jr. series created in collaboration with boutique builder Dirty Boy Pedals to bring their circuits to a more affordable, pedalboard-friendly format. It delivers rich sustain and harmonic saturation with dynamic cleanup via the guitar's volume knob, and includes the series' signature six-position frequency selector for shaping the fuzz's tonal character. As part of the wider Dirty Boy Jr. series alongside a Booster and an Overdrive model, it shares the boutique-derived circuit design philosophy of the original, full-size Dirty Boy pedals. Released in 2026 as a newly launched collaboration, it targets players wanting boutique-level fuzz character without the cost or wait of the original hand-built Dirty Boy units.
