What is the Spring Reverb Module, and How Does It Work?

Spring reverb module is a special module designed to replicate the sound of a spring reverberation unit. The original intention of a spring reverb back in the 1930s by the Hammond Organ Company was to create a realistic room reverb sound. However, the design has many shortcomings. Instead, it became its own unique sound that has found its way into organs, audio gear, guitar amps, and eurorack.

The spring reverb works by sending an audio signal into a metal spring before it is amplified and sent through the speaker. As the audio signal passes through the spring, it bounces off its surface to create an echo-like reverberation. The end result is rich, warm depth that adds ambiance and texture to any soundscape.

What is the Spring Reverb Module, and How Does It Work?

Various types of springs are available for use with Eurorack spring reverb modules, each with its own unique tones and characteristics. For example, short-long springs feature a “bouncy” sound, while longer springs provide a more “sustaining” effect. Additionally, you can also choose between steel or aluminum springs depending on the desired tone and resonance you want to achieve. Experimentation is key in finding the perfect spring reverb tank combination for your Eurorack modular synthesizer! Also, consider how the spring is mounted in the case. Will it be mounted face down or face up?

However, there are some limitations regarding which spring reverbs work with the Stoel Music System Spring Reverb module. Check the product listing for the complete list of compatible springs.

Exploring the Different Types of Springs You Can Use with Your Eurorack Spring Reverb Modules

Once you have installed your spring reverb module and the spring of your choice, it’s time to start connecting it to your modular synthesizer! To get started, you must install your spring reverb in an optimal location in the case. Skiff cases are not recommended unless you plan on using a very small spring. Keep the spring reverb as far away from the power supply as possible. It is possible to pick up unwanted noise. Use grommets to mount the spring reverb. It quiets any movement or vibration of the spring that is undesired. Finally, be sure that your spring reverb is mounted correctly. Some require different mounting orientations to operate properly.

Once the spring reverb is installed in the case, it is time to hook it up to the spring reverb module. The Stoel Music Systems Spring Reverb Module features two color-coded RCA jacks corresponding to the spring reverb. First, connect the power and install the module in the case. Now you can insert a patch cable from the output on your modular synth into the input on the spring reverb module. From here, connect a second patch cable from the output of the spring reverb module to one of your Eurorack modules or one of the inputs on your mixer. Now you’re ready to start experimenting and creating unique new sounds with your spring reverb module!

Effective Combinations with Other Effects

To really make your spring reverb module come alive, try connecting it to other effect processors such as chorus, flanger, and delay. In addition, you can insert other effects before or after the spring reverb in the audio signal path. When combined with these effects, a spring reverb can create sounds that range from warm and soft atmospheres all the way up to complete mayhem. You can also try routing your signal through multiple FX and then into the spring reverb module to give it some texture and character!

Another fun trick is to insert other modules into the feedback loop. For example, modulating CV Sources, like LFOs, modify the feedback signal. You can also insert filters, waveshapers, and other audio modifiers into the feedback loop. Experiment and see what happens!

Troubleshooting Common Issues with Spring Reverbs

One of the common issues with spring reverb modules is weak signal output. Sometimes this is because of poor patching or wiring, while other times, it’s due to a lack of input signal. Ensure all your connections are correctly wired and that you have enough power to drive your module.

The other major issue with spring reverb modules is noise. Under normal circumstances, there will be some noise. You hear ambient noise like guitar amps or audio gear with spring reverbs. However, excessive noise can occur if the springer reverb unit is not correctly installed. Make sure that the reverb tank is away from power supplies. Also, certain eurorack modules may cause interference with a reverb tank. Experiment by moving the tank around in your case to find the best placement.

Another common problem is undesired distortion. Make sure the signal is not too strong. Hot audio signals overdrive the limitations of the reverb tank, often causing unwanted audio. Use an attenuator or mixer to turn down the audio signal.

I hope these tips will help you in your journey into eurorack spring reverb! Enjoy the boooiiing.
