Nux B5RC - Refurbished

A wireless solution designed for "difficult" guitars

The Nux B5RC was designed to adapt to instruments that often cause issues with conventional transmitters: Strat-type guitars with recessed 6.35mm Jack input, Les Paul-type models with traditional jacks, as well as basses and electro-acoustics (ukuleles included). Whether your pickup is magnetic or piezo, active or passive, you benefit from a stable connection and a format that fits easily without hassle.

Smooth playing, instant pairing, and smart battery management

Once connected, the transmitter and receiver synchronize via automatic pairing: ideal for seamless soundchecks, instrument changes, and home recording sessions. The Mute mode quickly cuts transmission when you set the guitar down, and the Auto Sleep mode saves battery after 10 minutes of inactivity. Depending on the instrument, a 6.35mm TS Jack extension cable may be required to connect the transmitter.
