Acoustic preamplifier with 6-band EQ and anti-feedback notch filter. Based on the circuit of the esteemed Para Acoustic DI, the Align Equalizer combines our signature, high-graded FET gain stage with powerful tone-shaping EQ that injects richness and balance to any acoustic pickup signal. A 6-band EQ shapes the frequencies we found most useful for improving acoustic guitar pickups with the flexibility needed to cover other acoustic instruments effectively. Multi-instrumentalists can incorporate dedicated EQ pedals for level matching a variety of instruments and tailoring a specific EQ for each one. Variable high-pass filter for best sound and feedback control. Phase inversion for both passive and active pickups. 3 position gain switch for easy level control. Garret Null notch filter tames resonant feedback.
