I found Summit about 2 hours ago and love it! Thanks for your hard work.
The pickups are Lace Alumitones. They are ultra-quiet and articulate pickups and have no wire coils. The polished aluminum bar that you see is the conductor of the electromagnet. I also wired a ghost pickup system into the bridge.
I cut the pickup rings out of sheets of copper and melted silver dust into them. This gives a discoloration from the heat and splashes of silver on the copper substrate. I have been silversmithing for a few decades, but woodworking is always a challenge for me. When you mess up, you can't just melt it down and start over.
This is a build from several years back. The body is chambered walnut sandwiched between Brazilian rosewood that was not useable for an acoustic guitar. I made the pickup rings, switch mount, and truss rod cover from copper and silver dust. It's not all polished up because I have played daily for almost five years.
I've used gnome for years, about a month ago I decided to give KDE a try on my old spare laptop. Two days later it was on my desktop and work laptop. I am loving KDE.
