Thank you for viewing! This is a ZOOM MultiStomp (older model). There are no issues with the effects or button response. I will include a USB cable, which is not originally included. This cable is necessary for additional effects, so please use it! Included items are the main unit and the USB cable, for a total of two items. If you're looking for a compact multi-effects unit, this is for you! Multi-function multi-effects unit, equipped with an LCD screen. - Model Name: MS-50G - Brand: ZOOM - Type: Multi-effects unit - Input/Output Terminals: Mono input, Stereo output - Design: Japan - Display: LCD screen Thank you for viewing.
