AKG GB40 Guitarbug Features:
FlexJack swivel jack plug matching every guitar output
Extended frequency response optimized for guitar and bass
Integrated charging contacts
Optional CU40 charger for reduced operating cost
The Guitarbug's FlexJack swivel jack plug will mate with any type of output jack and is spring loaded to hold the GB 40 securely against the instrument. In addition, the GB 40 is so small it is almost invisible and won't be in your way while playing. Since the GB 40 sits right on top of the instrument's output jack, the noiseless on/mute/off switch and gain control are always within easy reach. Integrated charging contacts allow you to charge the battery quickly and easily on the optional CU 40 charging unit, without having to remove the battery.
Because this item is used at your mouth or ear, it cannot be returned once opened due to health reasons.
