TubeOhm - Jeannie
Product information "TubeOhm - Jeannie"
Jeannie is an 8-voice polyphonic DIY synthesizer by TubeOhm’s Andre’ Laska and Rolf Degen, who also worked with Sonic Potions and others. They really took their time to develop it during the past few years and now here is it, currently released in small batches. If it is out of stock, it will come back soon after.
Jeannie features 2 Oscillators, Noise, 2 Envelopes, a Multimode Filter, Waveshaper, 2 LFOs, Ring Modulator, FM, XOR, OR, and a Step Sequencer. The Oscillators can run independently or synced and feature the impressive amount of 945 different waveforms each! 2048 sounds programs can be stored on the SD Card.
New to the latest firmware is an adjustable Waveshaper per voice. Unlike in many other synths, the Waveshaper is located after the filter, what gives extremely interesting timbres and has its advantages.
The synth contains a digital effect processor with 14 different, adjustable effects.
TubeOhm are constantly improving the firmware at the moment, so you can expect updates and new features during the near future.
This is definitely an extremely interesting DIY project with a high price/performance ratio. Hopefully a little community will grow over time around that nice piece of gear.
It is coming with an acrylic case, but Erica Synths are manufacturing a very nice aluminium case for Jeannie, which can only be ordered at Erica: https://t1p.de/3n2of
DIY-Kit-Type:
SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder. 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.
