Have the right skills, tools and test gear to build your own modular synth, then our kits of parts may be just what you need. As a minimum, you will need to be able to identify electronic components, recognise when they need to be correctly orientated, to be able to use a small soldering iron and finally have access to test equipment. Some modules do not require the use of test equipment but any requirement will be in the 'Setting and Trimming' notes.
The kits include all required electronics components as well as pots & switches. The PCB, connectors and knobs are not included but available from Soundtronics as an option. Our front panel + matching back panel really finish off the module in a truly professional way. If you purchase the PCB and components through Soundtronics, then we will also support you with technical assistance just in case you get into any build difficulties.
We only source quality components and we even include the more expensive turned pin IC sockets as we feel the product justifies the extra cost both for reliability and serviceability. Our optional 1/4" jack sockets are by Switchcraft, yes you can save money by buying cheaper sockets hence us offering it as an option because we recognise they are a significant cost. We have standardised on Cliff KM20 knobs for all of our modules but again, as it's an option you can choose different knobs to suit your own preference. Finally, all components are available individually should you not need to purchase the whole kit.
