The IS400 Digital Hybrid Wireless system sets new standards for wireless guitar and bass. Flat frequency response, low distortion and compandor-free operation provides the closest thing to using a high-quality instrument cable. The system faithfully reproduces the lowest fundamental from a 5-string bass (low B) at 32Hz up to the very highest overtones and harmonics.
