Spring reverb

Spring-based reverb tanks weres a popular method of adding reverb to guitar amplifiers and other audio equipment in the 1950s and 1960s. Spring reverb works by sending the guitar signal through a transducer that excites a spring, and then capturing the reverberations that the spring produces with a pickup.

Spring reverb pedals are designed to simulate the sound and behavior of spring reverb tanks. They use digital or analog circuitry to emulate the spring-based reverb, and often include controls to adjust the reverb time, tone, and wet/dry mix. Some pedals even include a “dwell” control to adjust the amount of high-end frequency damping, which is a characteristic of the original spring reverb tanks.

Modern spring reverb pedals have the ability to switch between different spring simulations, some of them use real springs, others use a digital emulation of the spring, some pedals even allow the user to load their own samples of spring reverb recordings.

Spring reverb is known for its distinctive and natural sound, with a sense of space and depth, and a characteristic “boing” sound at the beginning and end of the reverb tail. It’s a popular choice among guitar players looking for a vintage and surf rock sound, but it can also be used creatively in many different genres of music.
