Frequenty Asked Questions
Do you offer build guides and documentation?
All available documentation can be found directly on the individual product pages. Scroll to the bottom of the page to find links to build guides and other relevant files (if available).
How can I access build documents for discontinued or older module versions?
Documentation for discontinued or older module versions is available in my Google Drive archive. Each module has its own folder containing older and relevant documents. You can can access the archive here.
Can I get help if my build doesn’t work?
Yes. You can contact me for support, and I’ll help you troubleshoot your build. Email: info at gurugarasynth dot com
What type of capacitors should I use for my Eurorack build?
Generally, for non-polarized capacitors, the specific type won’t matter unless the build documentation explicitly states otherwise. However, choosing the right component can improve the stability and longevity of your module. Here are our recommended guidelines:
- Power Bypass/Decoupling: Ceramic or polyester (box type) capacitors are the standard choice here and work perfectly.
- Audio Path & Filters: For circuits where audio passes through the capacitor (like a VCF), film capacitors are preferred for their stability and low distortion. Look for Polypropylene (MKP) or Polyester (MKS) types, such as those made by Wima.
- Precision Timing (VCOs): If you are building a VCO (like a 3340-based oscillator), the timing capacitor is critical for pitch tracking. Use high-stability, low-tolerance types like Polystyrene or Silver Mica. For LFOs, precision is less critical, so standard ceramic or polyester types are usually fine.
- Voltage Rating: While capacitors in these designs rarely see the full 24V difference between the +12V and -12V rails, it is best practice to use capacitors rated for 25V or higher. This provides a safe buffer and ensures the component operates well within its limits.
Pro Tip: Always prioritize the build documentation. If a specific material or value is listed, it was chosen by the designer for a specific performance reason.
What is the difference between a PCB + panel set and a full DIY kit?
A PCB + panel set includes the circuit board and front panel only — you’ll need to source and assemble all other components yourself.
A full DIY kit includes everything you need to complete the module, including all components, PCB, and panel. Some full kits are THT (through-hole), while others are SMD/THT hybrids. All SMD parts come pre-assembled at the factory, so no SMD soldering is needed.
