BOSS WL-20L Wireless Guitar System Used for about six months. ----------------------------------- No receipt, proof of purchase, or warranty. Includes only the main unit and a micro USB charging cable, no outer box or manual. Due to amateur inspection, I cannot check fine details or parts that require disassembly. Please refrain from purchasing if you are looking for a perfect item. Price negotiations are not possible. Immediate purchase and purchase without comment are welcome. First come, first served. Discounts available for combined purchases, so please check out my other effects pedals.
