  • BJFe Royal Jelly Pickup Boost (RJPB)

    BJFe Royal Jelly Boost is BJFE's first guitar pickup booster. It features controls for changing pickup resonance and volume.
    The tone created by the coils of a passive guitar pickup has resonant peaks at the edges of its bandwidth. This is due to internal and external capacitance, and how much and what kind of peak it is will also be affected by the load on the pickup. The shape and height of this peak creates various pickup output and tonal characteristics.

    Royal Jelly Boost can adjust this peak. The TB control is a treble boost that allows you to adjust corner frequency and boost level.
    The TC control creates an upper limit for the treble boost and controls the range in which peaks are created.
    The G control is a gain control that adjusts the overall boost level.
    The V control is the volume and adjusts the overall volume. This means you can adjust the volume even with high boost.

    This allows you to use it, for example, to strengthen the single coil, increase the gain with the G knob, round the high frequency response with TC, and widen the strength of the upper midrange with TB.

    You can also use Royal Jelly Boost to match the sound of the guitars when using two guitars. You can use it to match the volume while emphasizing the differences in the guitar's original sound.
