Joyo Jam Buddy II Gray Amplificador combo de modelação

Portable Guitar Amp with Multi-Effects, Bluetooth, and USB-C Recording

The JOYO Jam Buddy II is a battery-powered multi-effect modeling amplifier that combines a 16 W stereo speaker rig, 14 amp head models, 36 drum patterns, a 30-second looper, Bluetooth audio, and USB-C OTG recording in one 940 g unit. Guitarists wanting a single device for bedroom practice, lessons, and songwriting will find this model a complete grab-and-go rig. Three footswitchable channels (Clean, Rhythm, Lead) let players switch tones hands-free, while the integrated drum machine and looper turn the unit into a self-contained practice partner. Bluetooth streaming and the USB-C OTG audio interface add modern connectivity for jamming along to backing tracks.

What Sets This Amp Apart in the Mini Practice Category

Inside the 161 x 182 x 70 mm enclosure sit two 2" full-range 8 W speakers paired with a 76 x 46 mm rectangular passive bass radiator. The unit also includes a built-in metal smartphone/tablet holder, a press-and-turn multi-function knob with LED display, and a USB-C OTG audio interface that turns the amp into a class-compliant sound card for phones and computers.

Speaker System and Amp Models — Practice Anywhere

The stereo speaker configuration delivers a balanced frequency response for both guitar tones and Bluetooth playback, while the dedicated headphone output lets players switch to silent practice.

• Speakers: 2 x 2" (40 mm) full-range, 4 Ω / 8 W each — plus a 76 x 46 mm passive bass radiator

Effects, EQ, Drum Machine, and Looper — Tone Shaping Toolkit

Inputs, Outputs, and Battery — Modern Connectivity

The amp accepts a standard 6.3 mm TS guitar input and offers multiple output paths for stage, studio, and silent practice. A rechargeable lithium battery delivers roughly 5 hours of playtime.

Who Should Pick Up This Amp

This unit is the right choice for electric guitarists who want a single portable rig for home practice, lessons, songwriting, and travel without hauling a full amp and pedalboard. Bedroom players benefit from the headphone output, while gigging guitarists can use the line out to feed a PA for small shows. Songwriters get a built-in drum machine, looper, and USB-C OTG recording to capture ideas on the go, and teachers can hand students a rig that covers tone, rhythm, and recording in one box.
