GAMMA Cumulus 3-Way Reverb Effects Pedal

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.

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.
