Product overview A single B500K pushpull potentiometer with an attached circuit board, model number 0573, supplied as one piece. This unit combines a 500K Btaper pot with an integrated pushpull switch to add switching functionality to compatible electric guitars. Key benefits Restores or upgrades control: a worn or noisy potentiometer to regain smooth volume or tone control and reliable switching action. Builtin switching without extra routing: The pushpull mechanism provides an onboard way to change circuit states without adding a separate switch. Straightforward installation: Supplied as a complete unit with circuit board for easier wiring and clean, repeatable connections. Important attributes Resistance and taper: B500K specification (500 kiloohms, B taper) suitable for many electric guitar pickup configurations. Integrated switch: Pushpull type switch combined with the potentiometer for compact, functional control. Includes circuit board: Premounted board simplifies soldering points and wiring layout. Quantity: One piece, model number 0573. Compatibility: Designed for use with Epi Standardstyle guitars and other instruments with compatible control cavities and wiring layouts. How it helps Eliminates intermittent volume/tone problems caused by worn pots and poor contacts. Adds switching capability for alternate wiring options without modifying the instrument body. Keeps wiring neat and organized with the included circuit board. Typical use scenarios : a faulty volume or tone pot in an Epi Standardstyle guitar to restore reliable control. Upgrade: Add a pushpull function to enable an alternate pickup wiring option without installing an additional external switch. Custom builds: Install in a custom or modified instrument with compatible control cavity dimensions to provide combined potentiometer and switching functionality. Technical note Confirm cavity depth and shaft length requirements for your instrument before installation to ensure proper fit. Basic soldering skills are required to connect pickup leads and ground wires to the circuit board. Package contents One B500K pushpull potentiometer with circuit board, model 0573. This component is intended for use by musicians, technicians, and hobbyists familiar with guitar electronics and basic wiring procedures.
