Quality-made components deliver high-quality sound that'll even raise the most skeptical eyebrows among electronic-music enthusiasts. Plus, the Pocket Operator PO-12 runs so efficiently on just a pair of AAA batteries, that its standby time is measured in years. What's more, the PO-12 and the rest of the Pocket Operator line can sync to one another (and many other modular synths) over 3.5mm cables, so you can integrate them into a larger tabletop rig.
