The DR. Tone FTN101 PSU10 Power Supply is a must for any pedal-using guitarist. The PSU10 can power up to 10 pedals: 8 x 9 volt pedals and 2 adjustable voltage outputs (adjustable to 6, 9 or 12 volts). The PSU10 comes with 10 standard connectors (compatible with BOSS compacts for example). This is a great way to power your whole pedal board.
Note: check the voltage and current requirements of your pedals to make sure they are compatible with the PSU10 before connecting them.
