Many reasons why a battery box or any type of compartment needs to be fitted to a guitar, knowing the process before hand can minise wood tear out.

The owner of this guitar wants a sustaniac system fitted, it requires a battery pack to be installed to power it up.

Discussing with the customer and access that they want, decision has been made to go through the paint behind the trem area

Time to carry out 2 hrs.
Using high tack masking tape, we tape the the painted surface up to allow some planning and drawing.
Turning the battery pack upside down, we trace around its border so we can see how it fits.
We also need to check the topside area is clear, so we measure the total distance from the back of the guitar.
And check the front has nothing mounted in this area.
Also place the battery pack up against the rear, to make sure no relief cutouts are going to affect our routing.
We then draw our internal battery pack measurements, this is the area we need to remove.
Using a razor blade, we scribe the painted surface at the new marks to minimse paint tear out from the subsequent machining we are about to do.
We make a template to guide our router, here we are using the cnc laser cutter, if you dont have a cutter, these templates are available from many suppliers of guitar parts and or visit a local laser cutting business, they can cut some out of scrap material.

A template like this, you would expect to pay around 20 dollars to have it made for you.
The cicruit diagram that came with the system shows the need for a 9V battery.
Placing the battery pack that is going to be fitted, we find a acceptable and visually pleasant area to locate it.
The rear strap screw comes into this area, we need to mark the tape to indicate this so our battery box is clear when being installed.
Test fit the battery pack.
