The adapter you'll need to keep your Pignose 7-100 guitar amplifier from eating up battery power.
The regulated Pignose 7-100AR AC power adapter is made for the Legendary Pignose 7-100 portable guitar amplifier (see item #489050). The amplifier is powered by either 6 AA batteries (not included) or by this AC adapter, which stores inside the amplifier case.
Just plug the adapter into the wall and save on batteries when you're at home or anywhere close to an AC outlet. The regulated Pignose adapter is the preferred choice because it provides low-hum operation.
