Warm Audio Dirty Boy Jr. Booster
Warm Audio · pedal
The Warm Audio Dirty Boy Jr. Booster is built around the original Dirty Boy Ball Buster circuit, part of the three-pedal Dirty Boy Jr. series created with boutique builder Dirty Boy Pedals. It delivers up to 10dB of gain ranging from a transparent clean boost through to saturated, British-amp-style breakup, with dedicated Treble and Bass controls plus a three-position H-M-L frequency switch for shaping where the boost sits in the mix. As with its Overdrive and Fuzz Jr. series siblings, it brings a full-size boutique Dirty Boy circuit into a more affordable, pedalboard-friendly format. Released in 2026, it targets players who want a flexible always-on boost or amp-pushing pedal with genuine tonal shaping rather than a single fixed voicing.
