Specifications
What is the extra 6.35mm plug extender for?
The included 1/4-inch 6.35mm plug extension adapter helps the JA-05G fit more electric guitar jack layouts, including Strat-style, recessed, or angled output jacks. Use it when the amp cannot plug in smoothly or needs a better angle.
Can it connect to Bluetooth headphones? Is there a headphone jack?
No. Bluetooth is for playing songs or backing tracks from your phone through the amp only. JA-05G does not connect to Bluetooth headphones, transmit guitar audio out, or include a headphone jack.
What is this mini guitar amp best for?
JA-05G is best for personal electric guitar practice, bedroom playing, dorm rooms, travel, lessons, and quick warm-ups. It is a compact 5W practice amp, not for stage volume, full-band rehearsal, or bass guitar.
How long does the battery last? How should I charge it?
A full charge provides about 5 hours, or up to 6 hours under light to moderate use. Battery life varies by volume, effects, and Bluetooth playback. Use the USB-C cable with a 5V, 2A charger; chargers over 5V may damage it.
