Bass Rewiring
I decided to try my hand at playing the bass, but the one I had at home had a lot of noise, so I picked up the rewiring project my dad had been meaning to do. I replaced the potentiometers and capacitor, and made sure to keep the soldering cleaner than the previous version. I somehow forgot to take a video of what it sounded like before, but here's what the inside looked like when I started:

And here's what it sounded like when I was done! (This was in fact my second day playing the bass, so don't expect great musical talent...this is just to show the noise-free sound quality)
