Ever notice how a wah-wah and other vintage-style effects color your sound and mess with the tone of your other pedals, even when turned off? That's because many guitar effects aren't wired for a true bypass. This will muddy your tone, and cause other effects in the signal chain to lose volume.
Use this special triple-pole double-throw 9-lug footswitch to rewire vintage pedals or effects boxes. It allows unbuffered bypassing of the effect circuit without coloring the tone of the instrument or other components in the signal chain. The third pole can be wired to control an LED status light or other custom function. This is useful for stage performers, as it leaves no question if the "box" is on or off.
