Thank you for viewing. This is a multi-effects processor for bass that I purchased new about six months ago. I bought it as my first effects unit, but I'm selling it because I've decided to build a more serious pedalboard. It hasn't been used much, so I think you can use it as if it were new. - Model Name: B1X FOUR - Brand: ZOOM - Function: Multi-effects processor - Control Panel: Button type - Foot Switch: 2 foot switches - Back: Anti-slip pad - Color: Red Everything that came with it at the time of purchase is included. AC adapter is not included. ※Added on 11/11: AC adapter available for an additional 800 yen.
