HSS2020 Pocket Synthesizer / Effects

MicroDigitalMonophonic

$94

Ever wonder what a synthesizer would sound like if it glitched out in the most musical way possible? This pocket-sized wonder draws from that raw, unpredictable energy, evolving from earlier designs into a 2020 update that's perfectly tuned for on-the-go experimentation.

Run it on three AAA batteries for ultimate portability, with a simple power switch and mono audio in/out plus a headphone jack for private jams. It packs a digital monophonic synth engine with built-in filter, delay, and distortion effects—toggle switches shape synth tones and accents, while buttons handle sequencing, arpeggiation, and real-time tweaks; plug in external audio to mangle it with those same FX. Record up to three banks of sequences (with length and chaining options), erase or reset on the fly, and sync via trigger out or external input to pair seamlessly with Pocket Operators, Volcas, or any battery-powered rig. A tiny manual on the back decodes all the functions, keeping things hands-on and intuitive in its compact, colorful handheld form.

Since its release, folks have embraced its "damaged" aesthetic—lo-fi glitches and rhythmic quirks that spark creativity in jams, though some note the learning curve for deeper sequencing. It's a Gieskes standout for glitch-loving tinkerers who want affordable chaos without the bulk.
