Here's the super-fun hamheart featherduster synth box. There's a core oscillator with 3-way pitch range switch. There are four LFO's for modulation and a variable mod control knob that goes from subtle to screwy. There's also a great and unique filter which can be bypassed completely if you want. We like these little guys. They sound great and they're oh-so-unique. Each one has different artwork and we love that! Check out the new hamheart.com too!
