Cherub G-Tone GT-3 Three Band EQ Preamp with Under-saddle Pickup and Chromatic Tuner The CHERUB GT3 is a compact and great sounding Pickup System designed to mounted in acoustic guitars. Punching well above its weight, the GT-3 offers the performance of more expensive systems for a fraction of the price.

If you find your guitar feeding back - simply press the Phase Switch and the output signal is inverted 180 degrees. Additional fine tuning can be made with the Notch Filter. The GT-3 also features a highly accurate Chromatic Tuner with a HD high definition LED display module. Turning the GT-3 on and off is easy too - just plug your 6.35mm guitar lead into the input jack and the Preamp is on. To turn it off, simply remove the lead.
