The Fun Generation AirZone 5.8GHz Instrument transmitter disappoints with its sound quality, particularly when used with a bass guitar. During rehearsals, the bass seems to get lost amidst the overall noise (guitar, drums), and the transmitter appears to cut off lower frequencies, resulting in a glassy and thin bass tone lacking the expected depth and punch. It fails to deliver the necessary bass lows, body, and kick for a satisfying performance. By cable, it sounds as it should be. The bass amp Fender Rumble 500, bass guitar HB JB-62 SB. Will return it or resell it to my guitar player mate.
