- 9v regulated guitar pedal power supply.
- Compatible with most pedals.
- Low noise.
An official Biyang DC guitar pedal adaptor which is also compatible with other effects pedal brands (such as BOSS). Because it's specifically designed for pedals, and isn't just a general 9v adaptor, you shouldn't hear that annoying buzzing noise.
Save even more batteries by using a daisy to power more than 1 pedal.
Don't buy a cheap supply which isn't designed for effects!
