Electro-Harmonix Nano BassBalls
Electro-Harmonix · pedal
The Electro-Harmonix Nano BassBalls is a compact twin dynamic envelope filter, a classic EHX effect that sweeps two narrow filters under control of your playing envelope to create vocal, quacky, funky textures. Built primarily for bass but equally funky on guitar, it responds to picking dynamics to open and close the filters, and a distortion switch adds harmonic grit and bite. From smooth, vocal like wah sweeps to gnarly, distorted funk, it delivers the famous BassBalls character in a smaller enclosure. It suits funk, fusion, rock and experimental bassists and guitarists who want dynamic, expressive envelope filtering with optional distortion in a space saving pedal.
