Cherub G-Tone Acoustic Guitar Preamp Equalizer with Tuner – 3/4-Band Piezo Pickup for Guitar & Ukulele

The Problem: Acoustic Guitars That Sound Thin, Harsh, or Unbalanced When Amplified

Every acoustic guitarist who has plugged into a PA system or an amplifier has experienced the disappointment. The guitar sounds beautiful unplugged — warm, resonant, full of character. But through the PA, it sounds thin, harsh, or unbalanced. The low end is muddy. The midrange is honky. The high end is brittle. And there is no way to adjust the sound without a separate EQ pedal or a mixing desk that you may not have access to.

The problem is that most acoustic guitars with built-in pickups have either no EQ control at all, or a single volume control that does nothing to shape the tone. The solution is a preamp with a proper equaliser — one that allows you to adjust the bass, midrange, and treble frequencies independently to achieve the balanced, natural sound that your guitar produces acoustically.

The Cherub G-Tone Acoustic Guitar Preamp Equalizer is that solution. Available in 3-band and 4-band configurations, with a built-in chromatic tuner, it gives you complete control over your amplified acoustic tone — allowing you to compensate for the acoustic characteristics of different venues, different PA systems, and different playing styles.

3-Band and 4-Band EQ: Professional Tone Control

The G-Tone series is available in multiple configurations to suit different instruments and playing requirements. The 3-band models (GT-2, GT-4, GT-5, GT-6) provide bass, midrange, and treble control for acoustic guitar — the three frequency bands that have the greatest impact on the overall tone. The 4-band model (GT-3) adds a presence or upper-midrange control that allows for more precise shaping of the guitar's character in the mix.

For ukulele players, the GU-2 and GU-3 models provide 1-band and 2-band EQ specifically calibrated for the ukulele's frequency range, powered by a CR2032 coin battery for minimal size and weight impact on the instrument.

Built-In Chromatic Tuner: Always in Tune

The built-in chromatic tuner is one of the most practical features of the G-Tone preamp. Rather than carrying a separate clip-on tuner or relying on a tuner pedal, you can tune directly from the preamp — muting the output signal while you tune, so the audience hears nothing. The chromatic tuner is accurate to within ±1 cent, providing the precision that professional performance requires.

Easy Installation: No Drilling Required

The G-Tone preamp is designed for straightforward installation in the soundhole of an acoustic guitar or ukulele. The piezo pickup element attaches to the underside of the saddle or to the bridge plate, and the preamp unit mounts in the soundhole using the included hardware. The installation process requires no drilling, no routing, and no permanent modification to the instrument — the preamp can be removed and reinstalled as needed.
