This morning I was struggling to get the push-on knobs off my bass, so I went out to my garage for tool inspiration. The trick, of course, is finding a tool that won't leave a mark on the paint or knob itself. In desperation, I stumbled from my woodworking tools to my auto repair tools and found exactly what I was looking for! This tool is called a 'spark plug puller' and works like a charm. It gives you great grip on the two sides of the knob and is rubber coated as to not mar the surface. If I recall, they are pretty cheap at Amazon and/or your local auto parts shop. {} {}
Great suggestion. Was just postulating how to get some push-on knobs off without scratching the surface. Thanks.
Two: Screwdrivers, spoons, chisels, forks, knives, thin bars of steel, or insert suggestion here resting on two non-marring pads. Or you could purchase or build a knob puller. It is better to lift from the bottom and move the knob straight up the knurled shaft. It is easy to bend the shaft when pulling with pliers-like devices. That doesn't make anyone happy.
