Figure out what key the chord progression is and use a scale for that key.



Key: G Major
Scale Choises: G Major Pentatonic, G Ionian (Major), etc. (there are many more possibilities, but those are the two most common)

So how do you find what key it is in????
There are at least fifty of these threads a day. Read the theory sticky.
Someones knowledge of guitar companies spelling determines what amps you can own. Really smart people can own things like Framus because they sound like they might be spelled with a "y" but they aren't.
I think what you wanted to ask is, "How do you know what key a certain chord progression is in?"

Let the crusade be your guide.
