UHF NEXUS Wireless for Guitar & Bass
Meet UHF NEXUS, CFG’s stage-ready wireless system for guitar and bass. It runs on the 657-663 MHz UHF band, away from crowded Wi-Fi, with under 2ms latency, 7 color-coded channels, and up to 165 ft / 50 m open-air range.
Why UHF NEXUS
- Fast feel: under 2ms latency keeps your timing tight.
- UHF stability: 657-663 MHz avoids crowded 2.4GHz and 5.8GHz spaces.
- 7 channels: color-coded channels help multiple players run clean.
- Flexible pairing: one TX can feed multiple RX units, or one RX can be pre-paired with multiple TX units for quick swaps.
- Stage fit: 230° rotating 1/4" plug fits most guitar and bass jacks.
- Battery: up to 6 hours per charge from the 950 mAh battery.

Frequently Asked Questions
Does it work with active pickups?
Yes. If a very hot preamp clips, lower the instrument volume slightly.
Does it change my tone?
Active or buffered instruments should feel very cable-like. Passive pickups may sound slightly darker at the very top end.
Is there latency?
Latency is under 2ms, so it feels instant.
Will it interfere with Wi-Fi?
It runs on UHF 657-663 MHz, away from Wi-Fi and Bluetooth bands.
Can I use multiple systems?
Yes. Use separate channels and keep each pair a few feet apart.
Can one receiver use multiple transmitters?
Yes, for quick swaps. Power on only one transmitter at a time.
Can one transmitter feed multiple receivers?
Yes. Set receivers to the same channel and color.
Can I play while charging?
No. TX and RX cannot operate while charging.
What is the warranty?
2-year warranty and 30-day returns.
Important notes
- Lower amp volume when powering on, powering off, or swapping links to avoid loud pops.
- For tight jacks or strong active electronics, consider the CFG Air-Pocket holster.
