This Fender replacement cable restores the factory-style internal connection between an amp's speaker output and the speaker itself. It reproduces the original fit and function used in many Fender models, offering a compact 13.5-inch length, a right-angle 1/4" plug for secure chassis routing, and two snap-on speaker terminals for quick, reliable contact.

What exactly is included and how does it connect?

The cable comes complete as a single internal lead with a molded right-angle 1/4" plug on one end and two snap-on terminals on the other. The right-angle plug inserts into the amp's speaker jack or output, while the snap connectors clip directly onto the speaker studs or posts for a secure electrical connection.

How do I install it safely inside my amp?

Always disconnect the amp from power and remove tubes (if tube amp) before accessing the chassis or speaker cavity. Route the cable along the same path as the original lead, plug the 1/4" connector into the speaker output, and clip the snap terminals onto the speaker posts, ensuring polarity matches.

• Unplug amp and discharge capacitors when applicable
• Follow original cable routing to avoid pinched wiring
• Match polarity of speaker terminals to avoid phase issues
• Secure any loose wire to prevent vibration noise

Will this affect tone or performance?
