Bring on a torrent of delightfully wet sonic environments with the GAMMA Cumulus 3-Way Reverb. Cumulus conjures three distinct styles of reverb—Studio, Spring and Plate—that can add ambient vibe, drippy fun or shimmering dimension to your licks, riffs and solos. Cumulus is one of six stompboxes in our brand-new and exclusive GAMMA guitar effects pedals line—which also includes the Altas Boosted Overdrive, Bacchus Dynamic Driver, Eros Clean Chorus, Hades Metal Distortion and Narcissus Warm Delay. We’re Guitar Center, and we know guitar players, so we populated the GAMMA line with six effects that are absolutely essential for gigging. In fact, you can construct a versatile and professional pedalboard with the sextet of GAMMA pedals alone.

All pedals in the GAMMA guitar effects series feature stunning metal-flake finishes, gig-tough chassis and knobs, scrupulously curated circuitry and buffered bypass (for consistent tone and signal output), as well as a compact size that won’t devour real estate on your pedalboard. Each GAMMA pedal can be run from a 9-volt battery or power supply (battery and DC adapter not included). In addition, we are extremely aware that the last thing players want is for their gear to crumble under pressure, so the GAMMA line was designed to defy the rigors of constant use and to sound sensational every time you plug in to play.

Cumulus 3-Way Reverb Controls and Features

The trio of reverbs is selected with a handy switch, and Cumulus also offers controls for Mix, Tone and Decay. Pretty much everything you need to craft luscious reverbs for any musical situation is at your fingertips. GAMMA pedals are also designed to endure the hardships of real-world use. Electrical footswitching protects against audible noise and other glitching that can sometimes occur when a mechanical switch begins to wear out. Buffered bypass ensures a strong and consistent signal is sent to the other pedals in your chain, so there shouldn’t be any volume dips or other anomalies when you swap or add effects on the fly. The heavy-duty metal chassis and knobs are durable enough to withstand being kicked off stages, tossed into gig bags and any other abuses that can occur during live gigs, studio sessions and gear transport.

How Does the Cumulus 3-Way Reverb Sound?

Cumulus delivers three classic reverb types for guitarists. The surf-music-approved spring reverb is a must—not just for wave riders who desire the drip, but anyone who wants a vintage-like splash. Players wanting a more lush vibe can choose the Cumulus Plate setting, which emulates the rich, expansive sonics of old-school plates such as the EMT 140. The Plate setting also offers the longest decay of Cumulus’ three reverbs to produce near-cavernous ambience. A unique feature of Cumulus is Studio—a reverb that goes beyond the typical “room” setting to simulate the organic environment of a recording studio’s tracking room.

Power User Tips for Reverb Pedals

Moody and cinematic textures are possible by choosing Plate and turning Cumulus’ Mix control to its maximum setting. The fundamental attack of the source sound gets delightfully blurred by the huge wash, and the sound can get even spookier if you subtly blend in the reverb by using a volume pedal or add expressive wobbles with the tremolo arm of a guitar. Film soundtracks, anyone? You can also simulate the crash and rattle of physically kicking a vintage reverb tank—a favorite trick of surf guitarists—by choosing the Cumulus Spring setting and slapping your guitar strings.

Versatile Reverb

The Cumulus 3-Way Reverb provides a quick and simple way to bestow your guitar signal with ambient appeal. Some other reverb processors offer deeper parameters, but Cumulus is a perfect choice for getting it done fast at live shows—or even studio sessions. Choose your ’verb, adjust the Decay, Tone and Mix, and you’re off. While the word “gamma” denotes the third letter of the Greek alphabet, it can also stand for Cumulus’ trinity of classic reverbs, as well as three pertinent reasons why GAMMA guitar effects pedals deliver extraordinary tone, tough-as-a-tank manufacturing and fantastic value: They are crafted by people who love guitar, for everyone who plays guitar, and they are only available at Guitar Center.

Yes please. Spring has sprung!

My three favorite amps are all-tube, low-wattage affairs with great grit and tone control. And each and every one of them is dry as a bone. In the past of tried a number of the "real spring" pedals and some of the hipster shimmer pedals (which are AWESOME!), but I've always had trouble finding a simple, good sounding reverb to match with a guitar amp. Until now. The Cumulus is fantastic. Well built with high quality switches and pots, this little gem does exactly what it promises. The Decay and Mix knob make it a snap to set the size of the reverb and how far "back" the guitar is in it and the tone control is great for setting the mood. You want dark and brooding? Got it. You want bright and spanky? Done. And while the Spring was the reason I picked this one up, the Studio and Plate settings are both phenomenal additions and make it super easy to get much more subtle, modern tones. Overall, this is a great pedal and an incredible bargain for the price. Boutique performance for under $100? Yes. All day, every day.

Bad. Tons of noise.

Bought this in a pinch from a local GC because of the low price. I think expectations were in line with the pricepoint, and to be fair, the verb sounds fine. But the pedal generates way too much noise to be used in any signal chain I've tried, high gain or clean.

    Well built pedal in my opinion. Very versatile with three different reverb options in one pedal!

  • The most useless piece of crap I've ever owned.

    The reverb can barely even be considered useable, Ave the noise this thing puts out is beyond intolerable. This needs to go back to the "lab"😡

  • This is my second Gamma Cumulus Reverb.

    If your combo amp doesn't have a reverb tank in the bottom, then this is for YOU ! ! I have several small amps, Fender, Acoustic, even a G50 and this works great with all of them. Good for guitars and basses.
