"Simple jam session, testing out the PAiA Fatman Analog Synthesizer. The drums are from a Korg drum machine. The PAiA Fatman is a DIY Analog Synthesizer kit. It arrives… More» in a thousand pieces, and you build it. The included instructions are excellent, and this was a very fun build. I highly recommend PAiA’s products."
