Simon I’m thinking more acoustasonic style. Already planning control cavity access and pickup/string access and I’m aware of the battery needed. I’m thinking of keep the battery in the control cavity, possibly in a cradle or just taped down. I heard that wiring up a stereo output jack will allow the battery to be disconnected when it’s not plugged in, leading to longer battery life and I’m happy to take the whole plate off to access it when necessary.
