Warm Audio WA-DBJR-BOOST – Dirty Boy Jr. Booster Guitar Pedal

The Dirty Boy Booster Jr. is an official collaboration between Warm Audio and Dirty Boy Pedals, delivering boutique clean-to-mean boost tones with 10dB of gain. Premium all-analog circuitry preserves touch sensitivity and dynamic response while pushing amps from articulate cleans into saturated British-style breakup, natural compression, and fuzz-inspired textures. Dedicated Gain, Treble, and Bass controls offer flexible tone shaping, while the H-M-L “Freq” switch adjusts low-end response for tighter rhythm tones or fuller lead sounds across a variety of guitars, amplifiers, and pedalboards. Built with authentic Dirty Boy styling and true bypass operation, Jr. Booster delivers boutique-inspired boost tones in a compact, road-ready pedal format.

Clean-To-Mean Boutique-Style Boost: The Dirty Boy Jr. Booster was created in partnership between boutique builder Dirty Boy Pedals and Warm Audio, bringing the celebrated Dirty Boy boost circuit to more players in a compact format. With up to 10 dB of clean boost, added saturation and compression as the gain increases, and an H-M-L Freq control for flexible tone shaping, Dirty Boy Jr. delivers everything from articulate clean boost tones to rich, character-filled drive on any pedalboard.



Developed With Dirty Boy: Working closely with Dirty Boy owner Danny Gomez, Warm Audio carefully recreated the touch sensitivity, dynamic response, gain character, and tonal flexibility that made the original Dirty Boy Ball Buster boost a favorite among players. Dirty Boy Boost Jr. delivers the authentic feel and sonic behavior of the original boutique pedal known for everything from transparent boost to saturated British-style breakup, compression, and fuzz-inspired textures.



Detailed Frequency Versatility: With the H-M-L “Freq” control on Booster, players can shape low-end response for tighter rhythms, balanced articulation, or thicker lead tones across different amps and guitars. The additional treble and bass controls allow for fine-tuning of EQ. This variety of boosting and EQ controls help maintain clarity and control in crowded pedalboards with mixed buffered effects, where boosts can sometimes alter frequencies unpredictably.



True Bypass, 100% Analog Circuitry: Premium all-analog circuitry delivers authentic boost tones with true bypass operation for preserving your natural guitar and amp character.



Hand-Tested In Austin, TX: Like all Warm Audio gear, the WA-DBjr-BOOST is meticulously hand-tested and inspected by trained technicians with a passion for making music in Austin, TX USA.
