Nux C58RC

The NUX C-58RC is a 5.8 GHz wireless system for guitar and bass, designed for amateur musicians who want to play in rehearsals or on stage without a cable between their instrument and their amp or pedalboard. The transmitter and receiver pair automatically for easy setup, while offering additional settings when multiple wireless systems are in use. Its advertised range is up to 30 m, with a latency of 3.7 ms.

Key Features

• 5.8 GHz digital transmission—a band that is generally less congested than the 2.4 GHz band used by Wi-Fi and Bluetooth devices.
• Automatic pairing for quick setup, with a manual mode and channel-scanning feature in case of interference.
• Built-in tuner with automatic muting during tuning.
• Modes optimized for passive, active, or high-output pickups.
• Cable Tone simulation that replicates the capacitance of a 6.4 m instrument cable.
• Claimed battery life of 4.5 hours per charge, with a 3000 mAh magnetic charging case included.

Is it easy to use for rehearsals and concerts?

In automatic mode, the C-58RC pairs the transmitter and receiver directly, eliminating the need to manually select a frequency before playing. The OLED screens on both modules display battery level and channel information, among other details.

If interference occurs, pressing the SCAN/ACT button on the transmitter initiates a channel scan. Manual mode is also useful for setups requiring more control, particularly when a single transmitter needs to power multiple receivers.

Is it suitable for active guitars and basses?

The C-58RC operates in passive mode by default. For an instrument equipped with active pickups or one that delivers a high output level, active mode adjusts the input to limit the risk of clipping.

You should therefore check this setting when switching from a passive instrument to an active or particularly powerful one.

Can you tune without an additional pedal?

A tuner is built directly into the transmitter. A short press of the power button activates tuner mode and automatically mutes the output, allowing you to tune without sending the signal to the amp.

This feature can replace a tuning pedal if you don’t need the more advanced functions of a dedicated tuner.

What does the Cable Tone feature actually do?

The Cable Tone feature simulates the capacitance of a 6.4 m instrument cable. It therefore modifies the system’s response to mimic the electrical effect that a cable of this length can have on the signal, particularly with passive pickups.

This simulation can be disabled from the receiver. It is therefore not mandatory if you prefer to use the transmission without this emulation.

What is the expected battery life?

NUX claims up to 4.5 hours of battery life for both the transmitter and receiver. The included 3,000 mAh magnetic charging case recharges both modules when they’re stored inside, eliminating the need to plug them in separately after each use.

A dual-port charging cable is also included. For a long rehearsal or an entire evening of playing, it’s still a good idea to check the battery level before playing, as the advertised battery life may be shorter than the duration of some events.

Is it convenient to switch guitars during a rehearsal?

The transmitter’s 6.35 mm jack automatically cuts the signal when plugged in or unplugged. This reduces connection noise when you switch instruments without having to turn off the amp.

The transmitter’s compact design is also intended to leave room around traditional tremolo bridges and is suitable for modern or headless instruments.

What should you know before switching to wireless?

Operating at 5.8 GHz limits interference from the many household devices that use the 2.4 GHz band, but it does not guarantee a complete absence of interference. The channel-search function is specifically designed to switch channels if the radio environment becomes disrupted.

The manufacturer’s stated range is 30 m. As with any radio system, the actual usable distance depends on the environment and any obstacles between the transmitter and receiver.

Verification note: Information verified against the official NUX documentation for the C-58RC, specifically regarding the 5.8 GHz band, the 30-meter range, the 3.7-millisecond latency, the 4.5-hour battery life, the active/passive modes, the tuner, Cable Tone, and the charging case.
