Music Thing Modular - Spring Reverb Expander
Product number:
100127
Product information "Music Thing Modular - Spring Reverb Expander"
The passive Spring Expander adds phono sockets on a separate front panel plus adds a blend knob for brick/tank.
• This is a very simple passive expander for the revised Spring module, which brings the phono connections to the front panel — ideal for smaller cases — and adds a simple mix control to blend real spring tanks with the solid state reverb 'brick'.
• The main reverb module has phono sockets on the back, so you can put a reverb tank inside your modular case. Often, you might want to mount the spring tank outside the case; for small cases, or for access to the springs — stroking them or muting them or ‘preparing’ them in some way. This little 3hp expander makes that simple.
• The panel is designed to be reversible, depending how you want to arrange the cable to your spring tank.
• The expander also has a simple mix pot to blend the spring and brick reverbs together — this is a really nice effect, particularly when using feedback.
• Weird patch trick: If you use the expander with a brick, but without a spring connected to the front or back of the module, the spring drive circuit will overdrive massively (the spring pickup is part of the feedback loop of an op amp, so without it you get open loop gain). Fading across to spring and playing with feedback and EQ can get some really crunchy, squeaky extreme distortion that can be quite controllable with the blend control.
• If you want to know more about spring reverb than you ever thought possible, enjoy my Medium post Everything I know about spring reverb.
• This is a very simple build - just a potentiometer and a couple of wires soldered onto the PCB, but if you have any trouble the best place to find help is in the Spring Reverb Github Issues List. Remember to search for closed issues as well as open ones.
DIY-Kit-Type:
THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. Only trough-hole parts to solder. Make sure to check the build guide before you buy. For build guide, more info, videos etc. please check the buttons below.

Product Safety Information
Eurorack DIY Kits
Important Notice & Intended Use
Please read this safety guide before installation or use. This kit is intended for adult users experienced in electronics and modular synthesis. Assembly, including soldering, is required. Proper testing and installation are essential to ensure safe and functional operation. The completed module is intended for installation in a Eurorack-compatible synthesizer system powered by ±12V and +5V.
General Warnings
1. Electrical Hazards:
• Ensure the power supply matches the module’s specified voltage and current ratings (refer to the product manual). Incorrect voltage can damage the module and pose a safety risk.
• Never connect or disconnect the module while the Eurorack system is powered on.
• Wrong polarity can damage your module or system. Make sure the module is connected with correct polarity.
2. Heat Generation:
• The module may generate heat during operation. Ensure proper ventilation within your Eurorack case to prevent overheating.
3. Sharp Edges:
• The module’s faceplate and components may have sharp edges. Handle with care to avoid cuts or scratches.
4. Small Parts:
• Contains small parts that could cause a choking hazard. Keep away from children and pets.
5. Compatibility:
• This module is designed specifically for Eurorack-compatible systems. Connecting it to non-compatible systems may result in damage or malfunction.
Assembly Requirements
• Soldering skills are required to complete the module.
• Ensure a clean, well-lit and ventilated workspace free of flammable materials during assembly.
• Use appropriate tools and safety equipment, such as eye protection.
Testing
• Test the module thoroughly for shorts or incorrect assembly before powering it in your Eurorack system. When the unit has malfunctions due to incorrect assembly, the entire Eurorack system might be damaged. It's a good idea to test it in a separate case with only that single module.
• Use a multimeter or other appropriate tools to confirm proper functionality.
Installation and Use
• Mount securely in a Eurorack case using the provided screws.
• Use only the included or manufacturer-recommended power cable.
• Connect only when the power is off.
• Follow the module's user guide for instructions on operation. Do not exceed the input/output limits specified.
Responsibility
Users are solely responsible for proper assembly and testing. Contact manufacturer support for assistance if needed.
Environmental Safety
• Dispose of the module, its components, and packaging in accordance with local electronic waste regulations.
Liability Disclaimer
• The manufacturer or distributor is not responsible for any injury, damage, or malfunction resulting from improper installation, use, or modification of this product.

Manufacturer "Music Thing Modular"
Eurorack Modular Synth format. They are designed in Herne Hill, London by Tom Whitwell.
I’m a former journalist and magazine editor (Mixmag & The Face). In the noughties I ran the Music Thing blog, before working at The Times. Got into DIY electronics after attending a workshop with Tom Bugs, reading Handmade Electronic Music, playing with Arduino and building guitar pedals.
Contacting me directly is rarely a quick way to get help with a project or a technical problem. GitHub issue lists are a good place to start (Turing Machine, Radio Music), a search of MW DIY will often find answers, as will looking at the Facebook Synth DIY group.
