The Fishman AGP-2 and ABGP preamps are specifically designed for use with piezo-
electric pickups. Since piezoelectric pickups require specific electrical environments,
the AGP-2 / ABGP feature discrete input stages that maximize the full potential of the
pickup. Both units provide active gain control and fully buffered shelving style active
boost and cut for bass and treble. The center frequencies of these controls have been
selected for their relationship with acoustic instruments. The width of the bass and tre-
ble separation effectively provides a midrange control; boosting the bass and treble
controls simultaneously will provide an effective midrange cut or vice-versa. The
Preamp housing is made of rugged aluminum and weighs only seven ounces. 

The AGP-2 is designed specifically for acoustic string instruments including guitars,
violins, violas, cellos and mandolins. The ABGP offers the same features as its general
purpose counterpart, but has specially selected frequencies specifically chosen for the
acoustic bass guitar.
