PRODUCT INFORMATION
05G portable 5W plug-in guitar amplifier with effects and Bluetooth playback.
Portable Plug-In Practice Amp
Plug the JA-05G directly into your electric guitar and play without extra instrument cables. This compact 5W mini guitar amp is easy to carry for bedroom practice, dorm rooms, travel, warm-ups, and casual daily playing.
Built-In 4 Practice Effects
Shape your practice tone with Clean, Overdrive, Distortion, and Reverb effects. Use the EFFECT button to switch between Clean, OD and Distortion, and long press for about 3 seconds to turn Reverb on or off.
Bluetooth for Backing Tracks
Bluetooth lets you play songs or backing tracks from your phone through the amp, making it easier to practice along with music. Bluetooth is for audio playback only; it does not connect to Bluetooth headphones or transmit guitar audio out. No headphone jack.
Rechargeable USB-C Power
The built-in 3.7V/1500mAh battery supports up to about 5 hours of use per full charge, depending on volume, effects, and Bluetooth playback. USB-C charging cable included. Use a 5V charger only; chargers over 5V may damage the product.
Fits More Guitars with Plug Extender
Works with most electric guitars using a standard 1/4-inch 6.35mm output jack. An extra 1/4-inch 6.35mm plug extension adapter is included to help fit more guitar jack layouts, including Strat-style, recessed, or angled output jacks.
Cable-free practice setup
The direct 6.35 mm plug connects to compatible electric guitars without a separate instrument cable, while Bluetooth 5.1 plays backing tracks from a phone.
Portable playing position
The compact body stays close to the guitar, making it suitable for seated practice, warm-ups, dorm rooms and travel.
Rechargeable everyday practice
A built-in 1500mAh battery provides up to approximately five hours of use, depending on volume, effects and Bluetooth playback. Recharge through the USB-C port with a 5V supply.
