I'm new to the forum and this is my first post.

I am considering buying a m1a for my 1956 gibson J-45 Southern Jumbo. After reading the specs and various posts, I'm not certain if the volume control adjusts the total overall volume (can totally mute all the sound fed to the amp) or if it adjusts only the sound from the guitar body but not from the strings (can't totally mute ALL the sound to the amp?)

Can anyone clarify this for me?
