This is the sobbat A/B Breaker. It's an A/B line selector equipped with a buffer amplifier. It features two loops and a through function, enabling noise reduction in effector serial arrangements and simultaneous switching of multiple effectors with a single stomp. It evolves the usability and possibilities of your effector board. There are minor scratches and other imperfections. The screws for the back cover are missing. I'm selling it because I've acquired more gear. There may be slight crackling noise, but it is currently in working order. Please understand that this is a used item before purchasing. Those who are sensitive or seeking perfection should refrain from buying. This is for the main unit only. It will be shipped in a reused cardboard box. Please note that shipping may be changed to RakuRaku Mercari Bin. Thank you.
