If you've made a bass modification that you're proud to show off, or one that you look back on and laugh - let's see it. Here's my mod, which probably falls into the latter category. I made this crude thumbrest (you can see it above and near the bridge pickup) for my Gibson Ripper using very basic hand tools. Painted, glued and screwed - I love it! I learned to play bass with my thumb anchored on this ugly little piece of wood, God bless it. It's never failed me in 34 years.
