I only had a few holes to drill in my 339: Two under the bridge for the new wires, and two near all the knobs for a couple new controls.

I took some time before installing on the phone with Bryan at LR Baggs, designing a new wiring setup that would give me the controls I want. The CTRL-X is designed to work in tandem with one master volume pot. That created 2 options for us Gibson players- give up independent pickup volume control, or - have no volume control pot when in acoustic mode. (YIKES)

Bryan's expertise with the CTRL-X was a huge help in creating a new setup that would add a master volume to the existing plan, and I get to keep my very important individual pickup volume controls.

To keep everything on the guitar looking as close to stock as possible, I modified some parts and made a bracket to mount the new additional volume pot in the F-hole, underneath the

pickguard, with a wheel rather than a knob: so it can be reached but not seen.

Thanks to my dad, who assisted with the install but importantly- photographed along the way. Here's Claire from start to finish:

We've spent a few weeks working on getting it installed and working, and today it was all worth it! My dad's SRV strat now outputs electric as well as (really good!) acoustic sounds! It can even be plugged to a stereo cable that sends the two signals separately to two amps.

While we were in the guitar we chose to thoroughly shield the electronics cavity to protect the guitar from hum (normally caused by being near flourescent lights).

Here are a few shots during and after the setup:
