Warm Audio Dirty Boy Jr Booster

Original Boutique Pedals in Board-friendly Formats

The Dirty Boy Jr. Booster Pedal from Warm Audio offers a powerful mix of boost and overdrive tones in a compact form, breathing new life into your rig. Designed in partnership with boutique pedal company Dirty Boy and optimized for single-channel, vintage British-style amps, this stompbox delivers a high-headroom, 10dB clean boost to push your amp’s character into a natural breakup. Often found on many of Dirty Boy’s drive circuit offerings, the three-position Frequency switch supplies tighter rhythms and thicker lead tones to fully shape your guitar signal to your desired specifications, especially when tweaking the low-end response. Treble and Bass controls are also on hand to refine EQ, ensuring definition and command of your sound without the risk of unexpected frequency responses often attributed to boosts. Built with a premium all-analog signal path and true bypass, the Dirty Boy Jr. Booster preserves your original signal while injecting it with rich, transparent gain, and is sure to quickly earn its place as a mainstay on your pedalboard.

Expansive controls at your fingertips

Dirty Boy pedals have earned a loyal following among Sweetwater's tone gurus thanks to their wide dynamic range, and the Dirty Boy Jr. Booster is a worthy addition to that reputation. The pedal's Freq control’s versatile rotary switch offers three notches to suit your chosen playing style, giving you everything from tight lows to a relaxed yet focused midrange to a treble boost that accentuates the voice of your favorite British-style amp. Once you find your ideal Freq setting, the Bass and Treble controls fine-tune your sound to perfection, filling your tone with bigger sub-frequencies and top-end bite to push through your mix. Even more, at even its highest settings, the Drive control pushes your tone into fuzz territory while eliminating unwanted bass response, easily dishing out those classic ‘60s and ‘70s vibes with a simple turn of the knob.

Warm Audio x Dirty Boy: boutique-style stompboxes for the masses

The original Dirty Boy pedals were initially created by Alex Saraceno, father to guitar virtuoso and composer Blues Saraceno, to bolster the esteemed player’s fiery licks. Dirty Boy later became known as one of the first boutique pedal companies trusted by the likes of Tom Delonge, John Frusciante, Mark Lettieri, and Neal Schon. Since acquiring the company in 2024, product designer Danny Gomez has made it his mission to spread the availability of Dirty Boy pedals. Together with Warm Audio, the Dirty Boy Jr. pedal family does just that by reaching a wider audience of guitar players who want boutique-style sonics with a high level of accessibility, all within Warm Audio’s same high-quality standards that have turned their vintage-style compressors into mainstays for recording studios worldwide.
