Operation confirmed, initialized, and lightly cleaned.Mainly used at , but taken to a studio a few times. Therefore, there are minor scratches (especially on the back).Despite its size and weight fitting into the pocket of a gig case, it delivers sound pressure comparable to high-end amp simulators like Kemper and UAFX, and can be used for a wide range of tones from clean to crunch and distortion. It has sufficient potential for live performances and recording. I've tried various multi-effects units, and I prefer this over HELIX and BOSS. The touch panel usability also gives AMPERO the win. I believe the cost performance is outstanding.This is a used item, and to prevent swapping or trouble, returns after purchase are not accepted.Accessories:- Power cable- USB cable- Outer box (with traces of initial label removal)- Quick manual9V DC center negativePower consumption: 500mA Max273mm (W) x 143mm (D) x 51mm (H)1202gMulti-effects unitAmp simulator
