KORG A5 guitar multi-effects unit. Power-on and sound output have been confirmed, and there are no problems with basic operation. Each footswitch and knob operation also responds. This is an auction for the main unit only (adapter, box, and instruction manual are not included). The exterior has some scratches and minor blemishes from use, but it is in relatively good condition considering its age. Please check the photos for the condition of the back and sides. It has a thick, impactful sound typical of 90s KORG, and is an easy-to-use multi-effects unit with a full range of effects such as distortion, chorus, and delay. Recommended for home recording, studio practice, and as a sub-unit. Please purchase only if you understand that this is a used item. #koyane instruments
