Reverb Tanks

Spring reverb tanks are used to create a unique reverberation effect in guitar amps and organs. The reverberation effect is created when an audio signal created by a transducer is sent through one or more springs, the movement of the springs is then converted back into an audio signal by another transducer at the other end, creating the unique sound.

Reverb Tank - Mod® MN-8AB2C1B, Medium Decay, 3-Spring, Mini
Replaces: _AB_C1B Solid, sturdy construction Type: Short (3 Spring) tank Decay: medium decay Input: 10 Ω Output: 2,575 Ω Connectors: Input insulated/output grounded Locking: No lock Mounting: Horizontal/open side down Compatible amps include any reverb that uses _AB_C1B type tanks. The Mod Electronics Mini Series reverb tanks are made using the same high quality components as the larger 4, 8, and 9 size reverb tanks but have been compacted into the smallest possible size that still provides a lush sounding spring reverb. These tanks are the perfect size for amps without a ton of space, pedal boards, studio equipment, and Eurorack and other synthesizers. The Mod® Electronics Reverb Tanks are high quality upgrade units.

The Mod Electronics Reverb Tanks are high quality upgrade units. Some of the major differences between the Mod®s and other reverb tanks are that the Transducers are wired directly to their respective RCA jacks as opposed to current production tanks where Transducers are connected by a detachable plug to their respective RCA jacks. This makes the tanks less receptive to any outside interference. The original Hammond Accutronics tanks from the 1960s were also wired directly to their respective RCA jacks.

"TAD redefines Spring Reverberation. When the manufacturing of Accutronics Reverb cans in the USA has been announced to close down in 2008 TAD started the research for an own high quality production of the classic spring reverberation units. The goal was to create a drop-in replacement bringing back that stunning reverb sound that Fender made so popular since the early 1960s.
The TAD Reverb Cans achieve this goal and even more: deep and smooth reverb, no fluttering but wide frequency response with airy top end instantly inspiring to enjoy guitar playing. The rock solid mechanical design assures a very dependable and consistent quality performance exceeding any expectation. A drop-in replacement and upgrade as well for vintage as for modern reverb cans by size, performance and tone."
