It provides IR sync to wirelessly match the receiver and transmitter frequency, an audio Mute switch, battery life LED indicator and up to 12 hours of operation on a single AA battery. Can you really use only one guitar? Samson doesn't think you should have to make that choice. That's why the AG8 plug-in transmitter was designed with a custom, dual-position connector that can fit both Fender (Stratocaster) and Gibson-style guitar output jacks. Airline 88 Guitar also provides exceptional low frequency clarity ideal for bass guitars. It's even a great wireless solution for acoustic-electric guitars, electric violins and accordions. Offering frequency-agile operation, the system’s rack mountable CR88 Wireless Receiver provides 16 selectable channels for reliable performance no matter where you are. The receiver's True Diversity design minimizes dropouts, while tone key technology prevents unwanted noise when your transmitter is off or out of range.
