The AMT ACCL is a wired single microphone left-hand setup for the accordion. It mounts to the left-hand side of the instrument via the included installation hardware without the need to open the bellows. The ACCL is installed by simply removing the bass strap and cover. It is placed inside near the bass machine with a cable and connector placed on the outside of the accordion where convenient. It is suitable for use with the ACCW for installation of a single microphone in an additional instrument. The setup must be used with an AMT preamp or wireless system.
