I use a 9v battery for both and it works really fine.
i only have 1 battery in my guitar and i was under the assumption that both needed separate power to run.. but from my observations the battery runs straight to the boost. from there is the power getting shared from the Pup and the boost? the reason i do not know myself is because i did not install it; it came pre wired with my Edwards and it has only the one battery box on the back with 1 9v battery.
What are you saying?
The FET transistors on the MM04/JE1000 (and any other effect) need power (9v or 4,5v) to work. Thats why it need a battery.
yes i know they need power to run, im asking why is it that i only have one battery running the whole setup?
