Brought a jazz body from JJ for a project fretless and looking forward to work with TBer Timothy on some jazz modification project. Both will involved a battery route for the standard passive jazz package. I am just thinking, instead of a standard 9v boxy battery, can i use 4 AAA sized battery to make up the voltage? and mA? for sure the AAA size with allow more flexibility when i can lay them flat in the existing control route....well... just a quick thought and try to invite some brainstorm or opinions..
