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.

"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."
