The OBP-1s boost-only design gives you the tone shaping benefits of active electronics without losing the inherent sound of the instrument. The OBP-1s discrete, all-FET circuitry features up to 18dB of boost at 40Hz and 4kHz, creating a sonic environment high in dynamic headroom and low in noise.All FET designTwo bands of boostMaximum amount of boost: 18db, occuring at 40 Hz for the bass, and 4kHz for the trebleOutput impedance: 600 ohmIncludes stacked Treble/Bass pot.
