Swiff Audio WT09 Wireless Guitar System

This Swiff WT09a Wireless System is very, very mint - it has never ever been opened. Reverb won't allow me to list it as new since I am not a dealer, but what you will actually receive is a new-in-box wireless system. I am selling this because I already have two of these and I simply don't need a third. The extra photo you see in this listing is from one of the systems I already have in use.

Anyway, here's the manufacturer's bumf:

"The Swiff Audio WT09a is a compact wireless system designed for the cable-free transmission of guitar signals. Transmitter and receiver connect directly to instrument and amp via standard 6.35mm jacks, with no additional hardware required. The 1 megaohm input impedance matches the standard load expected by electric guitar pickups, preserving high frequencies, string resonance, and tonal character even for instruments with passive pickups. Latency stays below 4ms and THD below 0.04%, keeping the signal clean – and the playing feel immediate and responsive. LED rings on the transmitter and the receiver display signal level and connection status at a glance.

"The Swiff Audio WT09a operates in the 2.4GHz band with six selectable channels and automatic channel selection after pairing, reducing the likelihood of interference from other wireless sources in busy RF environments. Range extends to 30m line-of-sight, covering rehearsal rooms, studios, and larger stages without reconfiguration. Transmitter and receiver are clearly marked, and the rounded housing keeps the transmitter low-profile at the instrument’s output jack. The system transmits the full audible range (20Hz–20kHz at -3dB) with a nominal signal level of -10dBV at both input and output, matching standard instrument and pedal board levels without adjustment. At approximately 76g including the magnetic storage case, the complete system is lighter and takes up less space than a regular jack cable in a gig bag, while providing complete freedom of movement on stage.

"The Swiff WT09a suits guitarists, bassists, and other instrumentalists who want freedom of movement without the cable management of a traditional wired setup – whether they're switching quickly between instruments or running multiple systems in parallel at a live event. The 2.4GHz band is license-free internationally, keeping the system legally usable across markets without requiring any frequency coordination. The package includes a magnetic storage case, USB-C charging cable, and wrist strap, so the system travels and deploys as a self-contained unit. As a compact backup solution or primary wireless system for smaller stages and rehearsal use, the WT09a covers the essentials without unnecessary complexity – and without any loss in audio quality."

In the real world, this performs solidly and has a very good range. It's actually more range than most people need, but if you ever wanted to know what your amp sounds like from a block away this will take you there without any sort of lost or dropped signal. It's super quiet, batter life is long, and this system is really much better than it has any business being. That's why I already have two of them.
