why does a guitar pedal need a battery or an adapter when it’s already getting power from an amp?
In: Technology
I might add: some microphones are powered externally, by the mixer or amp. This is called “phantom power.” However, amps don’t power guitars or pedals, as far as I know. Those require external power.
Yeah, thats not how that works.
An electric guitar doesn’t get power from the amp. The electric guitar is generating very very small electrical signals by the strings moving over the magnets of the pickups. These signals go through the cord to the amp which _amplifies the poop out of them._ So unless the guitar pedal is passive and only works on the signal magnitudes as they come from the guitar, it needs some external power.
