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.
