Pro Cable Dramatic Non-Plated AC Adapter for Large Effect Pedal Board 800mA, 5-Port Splitter Pro Cable's signature non-plated power adapter Reputed to eliminate sound muddiness. Used once on stage, then only a few times indoors! Excerpt from the following site: ------------- This custom-made product is a non-plated AC adapter for large electric guitar boards, compatible with multiple effectors. This is an AC adapter exclusively for effector boards, built-in with an isolation transformer, manufactured by Star Denki, a top-class domestic company that has produced those ultra-high-performance transformers. There are no non-plated AC adapters in Japan, so this is the ultimate AC adapter for effector boards. This large, non-plated AC adapter specifically for effector boards, 800mA, is a trump card for those using effector boards with high power consumption, and can also be used for integrated effector boards. With this, transform the sound of your guitar's effector board into the best electric guitar sound, the sound of a bass guitar. This is achievable with a single, exceptionally superior, non-plated AC adapter specifically for effector boards. The 800mA size feels larger than the numbers suggest. At 800mA, it's for professional use and has full-fledged specifications. It measures 10.4cm (length) x 7cm (width) x 5.6cm (height). While it doesn't have great compactness, it has a stabilization circuit, so it has the great advantage of being usable for all effector boards under 800mA. The AC side power cable length is 1m, and the effector side power cable length is 1.8m. Important: ) When using a non-plated AC adapter, pay attention to the capacity. 800mA means it's a 9V adapter, so you can use up to 7.2W in total, but anything more is not possible. This should cover most effector boards. If you exceed the capacity, it's dangerous because the AC adapter doesn't have a breaker. Thank you for viewing. Type...Electric Guitar
