A pocket interface for guitarists who record dry ideas or practice with backing tracks on a phone. It cannot mute the dry signal, so amp sim apps are not a fit for it.

Overview
A direct monitoring circuit sends your guitar's clean signal straight to the headphones with no delay while also feeding the phone for recording. The Joyo plugs into USB-C or Lightning, needs no power or drivers, and clips to a strap.
Zero setup recording on a phone is the reason to buy it: plug in, clip it on and capture an idea anywhere. The unmutable dry signal rules out playing through amp sim apps, since you will hear both.
Who it's for
Songwriters and students who record dry takes or stream practice from a phone. Players who rely on app based amp tones need an interface that mutes the direct signal.
Pros and cons
- No battery or charging
- Zero latency direct monitoring
- Clips onto strap or belt
- USB-C and Lightning support
- Dry signal cannot be muted
- Not for amp sim apps
- Android needs OTG, not all models work
Performance notes
Latency is avoided because the clean guitar goes straight to the headphone jack before the phone, so what you hear is the dry instrument mixed with app audio. The LED shows when the input runs hot, and turning down the guitar volume clears it.
