Rocktron Rampage RFS1 Single On/Off Footswitch
Here's a nifty, one-button on/off foot switch. LED lights tell you the on/off status.
Description:
Internal 9V battery powers the LED, links to amp with a single, standard guitar cable (TRS 1/4" ends). This is cool, since most switches hold up fine, but the cable eventually shorts out. With this design, you can simply unplug the cable and replace it; Steel case construction with side-slides for locking two or more switches together.
