collapse expand iconDescription

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.

GAMMA 50

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.

Got more than I expected

I'm a tube amp snob. Or, at least I was… We recently moved into a multi-level home where my studio is on the ground level floor and the family room is on the second floor. As I didn't want to be dragging amps up and down the stairs all the time, I went on the hunt for nice little practice amp for the second floor. A buddy suggested the Gamma G50 and I glad he did! Out of the (very well packed!) box, the amp has a clean understated look and is big enough to house the 12" speaker without taking up a ton of space. A few things caught my eye immediately: the controls are very clearly labeled, the Bluetooth, aux and headphone controls/connections are right on the front panel and the baby blue Trueblue speaker is a beauty! MY only initial complaint is that the power switch is on the back, but it's a minor gripe. So – sound? I grabbed ESP Ted-600T first (EMG 60/81 pickups) and I was happily impressed. The first channel is fine. Volume and three well-voiced tone controls for bass, mid and treble. Good clean tone, but nothing unexpected. What was surprising was the second channel. The first thing I did was try out clean settings on each of the voicings, and I was blown away. Suddenly the tone controls sprang to life and I was able to everything from full bodied jazz tones to honky nasal spank to crunchy grind, and I as I increased the gain, it only got better. Light overdrive was wonderfully touch-sensitive and cleaned up well when I rolled back the guitar's volume knob (though the Rock and Metal voicings always had a cool amount of grit). I then twisted the gain to full STUN mode and went to town. Power chords were think and aggressive, leads had a great vocal quality and pinch harmonics rang out loud and proud on the Rock setting. The Metal setting also scoops out the mids in a very aggressive way to deliver a heck of a gutsy roar. And through all of this, the unassuming Bass, Mid and Treble knobs gave me great control over the shape uf the sound. I then swapped out a few different guitars including a tele, a sterat and a Rickenbacker and impressed by all. In the end I was able to get tones that I have never coaxed out of my more boutique tube amps and this little guy never made it out of the studio and up the stairs. Highly recommended.

Not that Impressed

It was disappointing. I was not a fan of the full clean tone channel which is really the only channel you can use to add reverb or delay into the mix with distortion… it's the "pedal platform" channel. The dirty channel wasn't great either. It did have a lot of headroom, but it didn't really feel loud enough to compete with bass and drums. I wanted to like this amp, but… eh. It's probably not bad if you're just starting on the guitar and your drummer and bassist aren't that loud. It did have Bluetooth.

    Sounds amazing just might need distortion pedal if the metal settings isn't enough.

  • Great pedal platform with a lot of head room

    I use it for home practice. It handles pedals well and can use Bluetooth to play backing tracks. Limited functions might be a con to some. Plenty of volume.

    My use case is unusual. I play a 3 string guitar tuned open G (like a cigar box guitar). I play hard rock / metal and write all my own music. I've been on the hunt for a unique and powerful tone with significant distortion. The rock and metal settings on the Gamma give my exactly what I was looking for - and the result is a very unique sound. I turn heads everywhere I go. I love this thing way more than I should! I've tried many different amps and pedals (including tube amps) but the voicing on the Gamma is a much better fit than anything else I have tried. Now truth be told, I am mainly leveraging the preamp/voicing of this amp as I take the headset out into a Bose S1. The result is a strikingly loud and powerful setup that can handle most indoor venues without breaking a sweet. This little amp has changed my game. Thank you Gamma!

  • One of the best budget amps I've ever owned!

    I use this amp to practice and play along with my favorite recordings. Overall I like the concept of the amp. Fit and finish is first class. But the volume controls are very delicate so the volume leaps from a whisper to a shout with very little adjustment. My Joyo amp is louder than this Gamma as well. There is a "frying bacon" sound that is too noticeable at any volume level with or without a guitar plugged in. I would say pass on this amp.

  • I bought it for the all analog circuit, love it so much

    The tone is amazing. Very touch responsive. The sweet spot on the clean channel seems to be right above half way. It's not too loud there. Good natural compression and punchy bass. Idk what the point of the headphone jack is. It has nos peaker cabinet emulation, so sounds awful.

    Is this a solid state amp or a modeling amp? Can the footswitch go between clean and dirt, or does it step through the voices?
