Purchased in July 2025. Used indoors at home for about 6 hours. I was able to use it intuitively even without the manual. Please see the link below for details. https://ja.manuals.plus/m-vave/tank-g-multi-guitar-pedal-manua I downloaded and used the PC software "M-EFCS for Windows OS" from the M-VAVE website. Fine parameter adjustments can be made without stress, making sound creation much easier compared to turning the knobs on the unit itself. I was concerned because I read online that "the solder on the switch at the right end often damages the battery because the battery pack is located under that switch..." I investigated. Fortunately, this product had a sponge-like measure in place. I am selling it to organize my belongings. It has only been used indoors and is in like-new condition. All accessories are included. Instant purchase is OK. Thank you.
