Overview

A clean-sounding preamp with extended EQ and anti-feedback control.

Rich, clear, and ultra-quiet, the Ovation OP-30 preamp raises the bar in its class. It features 3-band EQ with a bypass switch, a Mid-Shift control for selecting a midrange center frequency of either 450 Hz or 970 Hz, a Pre-Shape circuit for boosting bass and treble response while cutting rumble-prone frequencies below 40 Hz, and a battery status light. Equipped with an easy-to-read LED array, the onboard chromatic tuner works for standard, open, or altered tunings, and can be calibrated to non-standard reference pitches.
