Rev SPRING-636 - General Questions

Do you have questions about Rev SPRING-636?
You will likely find an answer here:

Spring reverbs are one of the first mechanical devices invented to recreate to the acoustic reflections of a room.
The concept is relatively simple: the audio signal is captured by a transducer, sent to one end of the spring (or several springs), and in this way creates a wave that travels through the spring length. When the wave arrives at an end of the spring, part of the wave’s energy is reflected and stays in the spring. It is these reflections that create the characteristic sound of a spring reverb. At the other end of the spring, there is another transducer that converts some of the motion in the spring into an electrical signal.

Input Impedance

Lets you select two input circuits to adjust the input sensitivity.


Controls the amplitude of the output volume.


Adjusts the volume of the input signal fed into the preamp and adds some beautiful germanium colored saturation when pushed up.


Adjusts the reverberation time. The longer the decay, the longer the reverb tails will be.


Controls the stereo wideness of the reverberated signal, mono on the left and stereo on the right.


Is a Dry/Wet control between the preamped signal and the reverberated signal. This lets you the possibility to process audio with the preamp only.

Pre Delay

Adds a delay to the input signal to add a distance feel and create echoed reverberations.

Pre Filter

The Pre Fitler shapes the input signal before reverberation with a resonant filter offering several modes and slopes.

Post Equalizer

Lets you tame or boost the frequencies of your reverb tails with two shelves and a parametric equalizer in a dub mix fashion.


This series of buttons offer different tank models to bring some extra degrees of versatility.
