Joyo Jam Buddy II Modelleringskombination

Joyo Jam Buddy II Black — Compact Modeling Combo for Practice and Travel

The Joyo Jam Buddy II Black is a battery-powered modeling guitar combo packing amp modeling, effects, a looper, and a drum machine into a 940 g floor unit. Three footswitchable channels cover Clean, Rhythm, and Lead tones. The unit runs on its own rechargeable lithium battery or via USB-C.

All-in-One Practice Rig Without an App

What separates this modeling combo from competitors is its app-free design — every parameter is edited on the unit via the LED display and a multi-function knob. The 14 amp models include Blackface, JCM, Dual Rectifier, and 5150 voicings, each with or without an overdrive stage. A metal phone mount doubles as a viewing station.

Amp Modeling and Effects Engine

Three independent channels store complete patches, so a player can recall clean, crunch, and lead sounds with one footswitch tap. The 3-band EQ plus dedicated Gain knob shape each channel.

• Amp Models: 14 voicings — covers clean jazz, blues crunch, British stack, American high-gain
• Effects suite — 9 types spread across Mod, Delay, and Reverb slots: flanger, phaser, tremolo, chorus, vibrato, analog delay, digital delay, hall reverb, church reverb
• Channels: 3 storable presets — Clean, Rhythm, and Lead switchable via onboard footswitches

Speakers, Power, and Physical Footprint

Two 50.8 mm full-range drivers paired with a passive bass radiator reproduce guitar and Bluetooth audio with surprising fullness. At 16 W total output the unit fills a typical living room.

• Speakers: 2 × 50.8 mm full-range, 8 W each, plus bass radiator — stereo playback for Bluetooth, mono for guitar
• Power Output: 16 W — adequate for personal monitoring and small jam sessions
• Dimensions: 161 × 182 × 70 mm — palm-sized floor format that fits most gig bags
• Weight comes in at 940 g, light enough for daily transport without fatigue

Connectivity, Battery, and Recording

Bluetooth streams backing tracks from any phone or laptop, while the USB-C OTG port sends guitar audio directly into a mobile device or DAW. A 2200 mAh lithium battery delivers roughly 5 hours of playtime per charge.

• Guitar Input: 6.3 mm TS jack — standard electric guitar connection
• Battery: 2200 mAh / 7.4 V lithium, ~5 h playtime, 3 h charge — true cable-free practice
• Bluetooth audio streaming — wireless playback from phone or laptop with a dedicated Music Volume knob
• Headphone Output: 3.5 mm stereo jack — silent practice with auto-speaker mute
• OTG Recording: USB-C — direct audio to phone, tablet, or computer

Who This Modeling Combo Suits

This modeling combo is the right choice for electric guitarists who need a portable, all-in-one practice rig that travels as easily as the guitar itself. Bedroom players benefit from the headphone jack and drum machine for quiet practice, while touring musicians gain a reliable backup amp.
