Setonix Synth Boing! - DIY Build

As many modular manufacturers come and go, we often are intrigued by the not so well known ones. Setonix Synth is one of these, and we have to say that they are coming onto the scene with a HUGE BOING! Located in upstate New York and started in 2021, Setonix Synth derives its name from a little cute marsupial from Western Australia. (thats pretty rad). 

We happened to be surfing ETSY one evening and came across the Setonix Synth Boing! by chance. It was a partial DIY kit and it was very reasonable priced. We ordered it up and waited for it to arrive. Upon its arrival, we knew it would be a fast build due to the SMD components being all tacked down. 

Setonix Synth Boing! - What is it?

The Setonix Synth Boing! is a discrete transistor based low pass gate with some grit. It is a light dependent circuit that uses vactrols and a JFET transistor input and output stages. The Boing also uses an active LED control circuit, thus allowing for negative feedback and some gnarly overdrive…. basically, its a kick ass 4hp module that everyone needs in their rack.
