Joyo Zombie II Halbröhre Gitarrenverstärker

Joyo BanTamP XL Zombie II — 20W Hybrid Amp Head with Tube Preamp

Built around a real 12AX7 preamp tube and a 20W Class-D power stage, this model delivers the tight, saturated high-gain character of classic American "Rectifier" designs in a lunchbox-sized chassis. The hybrid topology keeps total weight at 1.3 kg while preserving the spongy, dynamic response of a tube front end. The Zombie II is the right choice for guitarists who want authentic high-gain tones in a portable, gig-ready format.

Two Independent Channels and Bluetooth Streaming

Unlike the original, the XL version adds a second, fully independent channel with its own Gain, Tone, and Volume controls. A retro-styled Bluetooth antenna streams backing tracks from any phone or tablet, and the included one-way footswitch toggles between Clean and Overdrive without touching the front panel.

Hybrid Tube/Class-D Architecture

Hybrid design keeps this head light while still feeling like a tube amp under the fingers. The 12AX7 preamp tube provides harmonic saturation and touch-sensitive response, while the Class-D output stage keeps the amp efficient and cool-running.

\n
• Rated power: 20 W at 8 Ω, which provides enough headroom for small gigs and rehearsal with a drummer.
\n
• Preamp Tube: 12AX7 / ECC83 — single tube drives both channels for true tube character
\n
• Power Amplifier: Class D — efficient, lightweight solid-state output stage
\n

Two-Channel Design with Independent EQ

Six knobs give each channel its own Gain, Tone, and Volume, so the Clean channel can stay pristine while the Overdrive channel is dialed for saturated metal tones. The single Tone control per channel is highly sensitive — even small adjustments make an audible difference. There is no onboard reverb; use the effects loop for ambience.

\n
• Channels can be switched either from the front panel or using the included one-way footswitch.
\n
• Controls: 2× Gain, 2× Tone, 2× Volume — independent voicing per channel
\n
• Switches: Clean / OD, Bluetooth, Power — front-panel toggles for mode and streaming

Effects Loop, Bluetooth, and Silent Practice

The rear panel hosts the I/O for integrating this instrument into a larger rig or for silent home practice. A series effects loop lets time-based pedals sit after the preamp, the 3.5 mm headphone output includes a basic speaker-emulated signal, and Bluetooth 4.0 streams audio from any paired device.

\n
• A series effects loop with two 6.35 mm jacks allows for seamless integration of time-based pedals.
\n
• Headphone Output: 3.5 mm stereo jack — silent practice with cab-simulated signal
\n
• Speaker Output: 6.35 mm jack, 8 Ω minimum — drives external cabs
\n
• Footswitch Input: 6.35 mm jack — included one-way footswitch for channel switching
\n
• Bluetooth: Version 4.0 — wireless audio streaming from phone or tablet

Metal Players, Gigging Guitarists, and Bedroom Riffers

The Joyo BanTamP XL Zombie II is the right choice for metal and hard-rock guitarists who want tight, saturated high-gain tones without hauling a full-size amp head to the rehearsal room. Bedroom players benefit from the headphone output and Bluetooth streaming for late-night practice, while gigging musicians can pair it with a 4×12 cabinet for stage-ready volume. Players who already own a clean-channel amp and need a dedicated high-gain companion will find the two-channel flexibility especially useful.

Joyo and the BanTamP XL Series

Joyo is a Chinese manufacturer focused on guitar amplifiers and effects, with a catalogue spanning tube amps, acoustic amps, distortion pedals, and digital wireless systems. The BanTamP XL series evolved from the original BanTamP line based on customer feedback, adding channel-switching footswitches and independent per-channel controls. The Zombie II is the high-gain member of that family, modeled after American "Rectifier"-style designs.
