The OBP-1’s boost-only design gives you the tone-shaping benefits of active electronics without losing the inherent sound of the instrument. The OBP-1’s 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.
Design: All FET / Two bands of boost / 9 or 18 V
Pots: 2 separate potentiometers included – 1 for treble / 1 for bass
Maximum amount of boost: 18db, occurring at 40 Hz for the bass, and 4kHz for the treble.
Input impedance: 1 meg ohm
Output impedance: 600 ohm
Dimensions: 2.49 cm (W) x2.49 cm (L) x 1.50 cm (D)
