Mad Professor Ruby Red Booster Guitar Pedal with Treble Boost and True/Buffered Bypass

The Mad Professor Ruby Red Booster is a versatile guitar pedal that can function as a treble booster, clean booster, overdrive, or a combination of these sounds. Its carefully tuned treble circuit provides up to +15dB of treble boost, while the booster section delivers up to 40dB of gain, allowing you to add sparkle, push your amplifier, or create musical distortion at higher settings.

Flexible Controls & Buffer Options

The Ruby Red Booster features Master, Treble, and Boost controls for shaping your overall output, treble response, and boost level. An internal high-quality buffer switch lets you choose between true bypass and buffered operation, with the buffer particularly useful when running multiple pedals or long cables. The 1x voltage-gain buffer uses a 500kΩ input impedance and approximately 50kΩ output impedance to maintain a natural guitar response.

From Sparkle to Saturation

Whether you're looking for a focused treble boost, transparent straight boost, or full overdrive, the Ruby Red Booster provides dedicated settings for each application. The Boost control can be pushed for amp-like distortion, while the Treble control can enhance presence and definition. With a 9V operating design, 110dB signal-to-noise ratio, +40dB voltage gain, and 70Hz–7kHz 3dB effect bandwidth, it delivers extensive tonal flexibility for stage and studio use.
