Big sounds can come from small places.
And when the price tag (a mere 65 bucks, or 79 if you buy it assembled) is also tiny, we’re some very happy people indeed. Bastl Instruments‘ Kastle is a tiny modular synth that runs on three AAA batteries, which together are pretty much the same size as the device they’re powering. This small wonder is an open-source hardware oscillator that offers phase modulation, phase distortion and track-and-hold modulation along with two patch points. It’s DIY-friendly, travel-friendly and heck—look at the lil’ guy—it’s just a friendly piece of gear.
