The Legendary Dirty Boy "Ball Buster" Circuit

Originally designed by Alex Saraceno, Dirty Boy Pedals earned a reputation for hand-built boutique effects that combined vintage inspiration with innovative circuit refinements. One of the company's most celebrated creations was the Ball Buster boost circuit, praised by players for its highly responsive feel, dynamic interaction with tube amplifiers, and ability to transform clean sounds into harmonically rich British-style overdrive.

Working directly with Dirty Boy, Warm Audio faithfully recreated this sought-after circuit in the Dirty Boy Jr. Booster, allowing more guitarists to experience its signature sound in a compact and dependable stompbox.

More Than a Clean Boost

While the Dirty Boy Jr. Booster excels as a transparent clean boost, its capabilities extend far beyond simply increasing volume. At lower Gain settings, it enhances clarity, presence, and articulation without significantly altering your guitar's natural tone. As the Gain control is increased, the pedal gradually introduces natural compression, harmonic richness, and amp-like saturation that responds organically to your playing dynamics.

The result is a highly musical boost pedal capable of everything from subtle tone enhancement to aggressive British-style drive, making it equally useful on stage and in the studio.

Comprehensive Tone Shaping

The Dirty Boy Jr. Booster provides intuitive controls that allow players to tailor the pedal to virtually any guitar, amplifier, or pedalboard configuration.

• Gain – adjusts both output level and saturation.
• Treble – shapes the high frequencies from transparent presence to classic British bite.
• Bass – adds focused, musical low end without becoming muddy.
• H-M-L "Freq" – three-position switch for selecting tight rhythm response, balanced voicing, or thicker lead tones.

This flexible EQ section allows the pedal to perform equally well with single-coil or humbucking pickups and across a wide variety of amplifier types.

Designed to Work with Your Amplifier

Unlike many traditional boost pedals, the Dirty Boy Jr. Booster was specifically voiced to interact naturally with the input stage of your amplifier. It responds directly to picking dynamics and your guitar's volume control, allowing players to clean up or increase saturation simply by adjusting their playing technique.

This organic response gives the pedal the feel of an additional gain stage inside the amplifier rather than a conventional external boost pedal.

Ideal Applications

The Dirty Boy Jr. Booster is suitable for a wide variety of playing styles and performance situations.

• Transparent solo boost
• Adding sparkle and presence to clean tones
• Pushing the front end of tube amplifiers
• British-style overdrive
• Natural compression
• Fuzz-inspired harmonic saturation
