Some active circuits produce a peculiar noise by boosting the high-frequency range, but Kent Armstrong's preamplifier can suppress such noise while still giving a thick ensemble with a clean sound. Rather than artificially enhancing the instrument with the power of a circuit, the midrange is more like a preamplifier that brings out the true power of the instrument, providing the appropriate compensation for your playing style, producing a tone that is best suited for fingerpicking, slapping, pick picking, and many other styles of playing. Also, in terms of low frequency, some basses have strong boosting power, making you feel that the bass is very good on its own. Still, when used in a band, the low frequency is blurred, and all that is there is the volume that destroys the ensemble. Still, this Kent Armstrong preamp has a tight, and Kent Armstrong preamp is a natural boost to the low end of the instrument, rather than the physical low end you get from a low-B or low-F# on a multi-string bass. Some people avoid instruments with active circuits because they sound filtered. Still, since the circuit design emphasizes bringing out the best in the instrument it incorporates, each circuit functions naturally like the tone of a passive circuit.
