The boosters are based on the BJF Little Red Trebler and Red Rooster Booster, connected in that order and with a master volume control. You can use the pedal as a treble booster, a clean boost or an overdrive unit or any combination of the above. Also it can be used with or without the buffer.
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.
Input impedance: approximately 500K Ohm’s Recommended output load: 50K Ohm’s or higher, effects output and buffer output Current consumption @ 9V DC: approximately 6mA DC supply voltage range: 8-18V Voltage gain: approximately +40dB Treble boost: peak +15dB@4KHz Signal to noise ratio: 110 dB Effect 3dB bandwidth: 70Hz to 7KHz True bypass or buffered (switchable inside the pedal) POWER REQUIREMENTS: 6F22 9V battery or DC eliminator 2.1 mm plug center negative and positive sleeve. NOTES: RRB is protected against wrong DC eliminator polarity. Fuzzy sound is a sign of low voltage. Maintain recommended voltage for best results.
