Product Description

The Feedback Master features a phase inversion control and two precise Garrett Null sweepable notch filters to accurately locate and eradicate feedback from top and air resonances without destroying your tone. The circuitry is all-analog pure class A from end to end to provide great tone quality. It works with virtually any pickup (active or passive) and includes a belt clip and mic stand adapter.

The Feedback Master is the best-sounding and easiest-to-use feedback remedy available for acoustic instruments.

Features
Two proprietary Garrett null sweepable narrow-band filters easily locate and damp air and top feedback resonances, controlling feedback without sacrificing tone

Phase inversion switch for additional feedback control

Adjustable gain for optimum signal level and lowest noise

All analog pure class A discrete circuitry makes it utterly transparent and quiet

Works as a standalone buffer-preamp with virtually any active or passive pickup

Includes mic stand adapter and belt clip

Recommended Use
The Feedback Master is recommended for acoustic players that experience continuous or severe feedback problems with their amplified instrument, or for performers in especially loud environments. While the Para D.I. includes controls that are capable of eliminating minor to average feedback, the Feedback Master is specifically designed for situations in which feedback is incurable with a normal preamp. Never the less, the Feedback Master features extremely quiet circuitry and all-discrete class-A design, making it a great option for normal applications.

The Feedback Master will work with any pickup; active or passive. It includes a gain adjustment knob, allowing it to work well with almost any stringed instrument. The EQ setting for this preamp is flat; it will not alter the amplified tone of your instrument.
