Guitar Pedal and battery mAh question

[battery9000]

Hey guys, quick question. I've got a multi-fx guitar pedal, and I'm wiring it up to a 9v battery. Now the power adapter for it is 9v and 300mAh, so I'm wondering if a typical alkaline 9v battery (Energizer brand) will work? I've gotten the pedal to turn on from the battery, but I want to know if the difference in mAh (if any) will make a difference or could potentially damage the pedal.


Thanks all

The 9v used in the fire alarm typically gives you 565 mAH so you should be fine.

For 60 - 90 minutes. Then you will need a new battery.

Cheaper in the long run to buy a little 9 volt wall wart.
