Mad Professor Ruby Red Booster (RRB) is a combination of two boosters and a switchable buffer.
The two boosters are based on the much sought after BJF Little Red Trebler and Red Rooster Booster, connected in that order and with a master volume control. The RRB can be used as a treble booster, a clean boost or an overdrive unit or any combination of the above. Inside the pedal there is a switch for a high quality buffer. You can set the pedal for true bypass mode or "buffer on" in bypass mode. The Treble Booster is a fine-tuned booster for just the right treble frequency with carefully designed bandwidth and an optimized slope of bass cut. The booster circuit is designed to overdrive the amplifier inputs from nice shimmer to heavy overdrive, thanks to the massive 40dB of boost. The booster is tuned so that it produces musical distortion by itself on higher boost settings. You can control the total level of the two boosters with the Master Volume control and also use the Master Volume to achieve distortion from the unit.
The easy to use Mad Professor Ruby Red Booster must be the most versatile high quality booster on market. Build the Mad Professor way: small footprint and big tone.
