GAMMA amps, with their premium True Blue High Headroom speakers and well-conceived all-analog design, provide superior sound quality, clarity and surprising performance volume in a simple-to-use package. The quality, punch and solid performance make them a choice that can serve as a handy grab-and-go pedal platform for gigs and practices, an extraordinarily versatile amp in your home recording studio or as a great starter amp for your favorite aspiring guitarist. The GAMMA G50 is designed to deliver unprecedented clarity, quality and versatility in an all-analog, lightweight, dual-channel, 50-watt, 1x12 amp that punches far above its weight class. Loaded with features like Bluetooth connectivity and multiple amp voices, it makes every player's musical life easier and more fun. The Acoustic Control GAMMA G50 is a great choice for everything from serious practice to professional gigs at local venues.  

GAMMA 50 True Blue Speaker

High Headroom From a Massive Magnet

The single, most salient feature of the GAMMA Series is the custom-designed, premium True Blue speaker at its heart. The GAMMA G50's 12" speaker features a large, 40 oz. (1.3 kg) magnet, the largest in its class, for fast response and high headroom, combining efficiency with remarkable clarity. Its surprisingly high maximum volume makes it not just capable as a band practice amp, but it also has what it takes to more than hold its own at gigs. The G50 is a superb pedal platform and produces an extraordinarily satisfying playing experience.


From Pedal Platform to Multiple Personalities

The GAMMA G50's pristinely clean "Blue Channel" (Channel 1), was specifically designed with a clear, accurate voicing and quick response that makes it an ideal pedal platform, whether you’ve curated a pedalboard of your favorite stompboxes or are using it as the final destination for a multi-effects unit or digital modeler. Channel 2 has four carefully crafted, exceptionally dynamic voices, so that you've got virtually the entire history of guitar music available. This versatile channel provides Clean, Blues, Rock and Metal voicings that move effortlessly from twang to shred. Channels switch via a front panel button or an optional footswitch, connected to the available rear-panel jack.

GAMMA 50 Controls

Easy Control for Tweaking Your Sound

The Blue Channel is simplicity itself. Designed from the beginning to be a superb pedal platform, all this channel needs is a Volume knob and a 3-band EQ. The player lets their pedalboard do the rest. The multiple voices of Channel 2 feature a Drive knob, for dialing in just how saturated you want your sound to be, a Volume knob to balance with the Blue Channel and it shares the amp's 3-band EQ with the Blue Channel. This setup provides just enough control to easily find the tone you want, without getting overly complicated.

GAMMA 50 AUX Inputs

The I/O You Want

Lightweight, compact and versatile, the GAMMA G50 goes far beyond being that great first real amp players always remember, to being a powerful addition to the toolkit of any gigging or recording guitarist. With the power and punch of the True Blue speaker and a smart selection of features that matter, this is one amp that can go the distance—all the way to the stage.
