Power supply that works with most common guitar and bass effects.
The general purpose DC 9 V power adapter PSU-SB from Behringer powers most guitar or bass guitar stomp boxes and effects pedals. This adapter provides a 100 mA current to power even digital products. For connection, it features a typical DC-type 2.2 mm plug with negative tip and positive sleeve. Check your device's milliamp requirements, and remember that it's okay to feed it somewhat more milliamperage than it needs, but not less.
