The Warm Audio Dirty Boy Jr. Booster is a compact analog boost pedal for players wanting everything from transparent gain enhancement to saturated vintage-inspired drive tones. Developed alongside Dirty Boy Pedals founder Dany Gomez it recreates the sought-after Ball Buster circuit with responsive dynamics and flexible EQ shaping. With up to 10dB of clean boost available the pedal can strengthen your core tone push amplifiers into natural breakup or add extra presence to crowded pedalboard setups. The H-M-L frequency switch works alongside dedicated Treble Bass and Gain controls to shape the pedals low-end response and overall character. You can tighten bass frequencies for articulate rhythm work or add extra fullness for thicker lead tones without losing clarity. As gain increases the pedal introduces natural compression harmonic saturation and fuzz-inspired textures while remaining touch-sensitive and expressive. Finished with true bypass switching and authentic Dirty Boy styling the Dirty Boy Jr. Booster delivers boutique-inspired boost tones in a compact road-ready design.

Brand
Warm Audio
Warm Audio began with founder Bryce Young’s aim of making the sounds of classic recording equipment more accessible through recreations of well-known analogue designs. The company remains rooted in studio gear, with microphones, preamps and compressors alongside a focused guitar-pedal range. Centavo revisits a sought-after overdrive, Foxy Tone Box is an octave fuzz, Mutation Phasor II is an optical phaser and Warmdrive is an amp-inspired overdrive. JustPedals listings include these models alongside ODD and WA-CV Centavo. The pedal line carries the company’s broader approach into guitar effects by pairing familiar circuit references with practical modern formats.

Boost Pedals
A boost raises signal level without deliberately creating a new effect waveform. Clean boosts emphasise level and headroom, while coloured boosts reshape bass, midrange or treble and may add mild clipping at higher settings. Placed before a gain stage, the extra level changes how that stage distorts; placed later, it can provide a volume lift if sufficient headroom remains.
Tags
Analogue
The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.
Bass
Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.
True Bypass
Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
