The PedalFarm B-1 is a classic germanium booster with extended features that make it one of the most versatile pedals of its kind. The B1 uses a single germanium transistor to produce up to 24db of boost, and 17 possible frequency cutoff points to choose from.
One large knob controls the boost, and a single three-way toggle switch on the front selects either a high or low frequency settings. Internal dip-switches give you 8 frequency choices for each setting. The center position is the classic Range Master treble booster frequency. This pedal features true-bypass switching, top mounted jacks, and red LED indicator. Power is supplied by either a 9 volt battery or DC adaptor. The battery compartment is located behind the back cover. The battery will be disconnected when either the input jack is unplugged, or a power adaptor is plugged in.
A three-way toggle switch on the front selects between high and low frequency settings, with the classic treble booster frequency in the center switch position. Internal dip-switches allow you to choose the “high” and “low” frequencies available on the toggle. 8 frequency choices are available for each setting. There is a chart on the inside of the enclosure cover for reference.
On the inside of the pedal, there is a BIAS switch with settings for 66% (default) and 50% bias points. This is intended as a “set it and forget it” optional modification. Check it out to see what works for you, or just leave it on the default setting, and ignore it. 66% is generally considered the optimal classic treble booster bias point. It produces an asymmetrical waveform that will swing about 66% positive and 33% negative. This is the default setting for this pedal. Biasing at 50% produces a more symmetrical waveform that will boost your signal evenly on both sides of the wave.
