Step 4: Observations about the Original Build
At this point, I just wanted to share why I thought this was a good idea, and figured this would be the best place to solicit alternative ideas. These fret buttons aren't flush on the bottom (picture 1) they're hollowed out a bit to allow for the jelly switches that actually control the guitar (picture 2). When they rest on the gelly switch (picture 3) it seemed like the simplest solution was to fill in the buttons a little bit.
However, number 1, as I'll mention later, I used 4 layers of business card stock, but perhaps 3 is a more prudent number. Number 2, I don't know much about electronics. Is there a better way to manipulate this setup? Comment below!
