PRODUCT DESCRIPTION
- The switch knob of your element switch can sometimes wear out or get lost. This is unfortunate, but fortunately easy to solve. The Boston LI-390 is an inexpensive replacement for worn and missing switch knobs. This is the ivory version that goes well with ST-style guitars with a retro look.
