Joyo BA-30 Vibe Cube Black — 30W Micro Bass Combo Amp for Practice, Livestream and Travel

The Joyo BA-30 Vibe Cube Black is a compact 30W bass combo amplifier built for those who need strong low-end response from something that fits easily on a desk or in a backpack. Inside the cube, a 4-inch (102 mm) full-range speaker and a 113 x 113 mm passive low-frequency radiator work together to deepen bass and tighten transients, giving the amp punch and clarity beyond its size. At just 2.7 kg and 183 x 165 x 216 mm, the BA-30 is made for bassists who move between bedroom, studio and small stage without hauling a full rig.

How the Vibe Cube Stands Out in Micro Bass Amps

Most small amps offer basic EQ and clean sound. Here, a sweepable MID FREQ selector (200 Hz to 2000 Hz) is layered atop the usual Bass, Mid and Treble controls, enabling midrange sculpting found in bigger combos. A dedicated OTG volume knob with Type-C USB-C port turns this instrument into a plug-and-play audio interface for phones, tablets and computers. Bluetooth 5.1 streaming enables wireless backing-track playback for rehearsals and live sessions.

Tone-Shaping Controls — Player Benefit

Bass tone depends greatly on the midrange, which is why the Vibe Cube offers more than the standard three-knob EQ. Use the MID FREQ selector to target the right frequency for scooping or boosting, while the dedicated compressor knob levels out slap pops and fingerstyle volume swings before they hit the speaker.

• Bass: dedicated Bass knob — shapes low-end weight and keeps the mix clean
• Mid: Mid level + MID FREQ selector (200 Hz – 2000 Hz) — lets users pinpoint the exact mid band to adjust
• For slap and pick styles, adding articulation and string definition is easy using the Treble knob.
• Compression: built-in compressor with dedicated knob — smooths transients and balances playing dynamics

Speaker and Output Architecture

The cabinet design lets the 4-inch driver deliver full bass response. While the full-range speaker handles mids and highs, the passive radiator reinforces lows without the port noise of a traditional bass-reflex. Plugging in headphones via the 3.5 mm output (32 Ω impedance) supports silent practice any time.

• Speaker: 4-inch (102 mm) full-range driver, 30 W — covers the entire bass spectrum from a single compact driver
• By using the 113 x 113 mm passive low-frequency radiator, the amp extends low-end depth and tightens attack for modern and classic tones alike.
• Headphone Output: 3.5 mm jack, 32 Ω impedance — full-range silent monitoring ideal for late-night sessions
• Channels: 1 channel — single, streamlined signal path for quick setup

Connectivity, Power and Portability

Modern bassists expect more than a basic 1/4-inch input. The Vibe Cube includes a full I/O panel in a portable 2.7 kg enclosure. Bluetooth 5.1 streams backing tracks wirelessly, while the OTG Type-C port delivers a latency-friendly signal to your phone, tablet or DAW. Power comes from the included 20 V / 2 A AC adapter or from any USB-C PD 2.0+ power bank rated at 65 W or higher for portable, cable-free setups.

• Bluetooth: version 5.1 — low-latency wireless streaming of backing tracks and reference audio
• OTG Recording: Type-C USB-C port with dedicated OTG volume knob — plug-and-play recording to phone, tablet or computer, no external interface needed
• Power: AC adapter 20 V / 2 A (40 W) or USB-C PD 2.0+ power bank at 65 W+ — flexible options for home, studio or travel
• Carrying is easy thanks to the 2.7 kg weight and the sturdy top handle, while the ABS shell with leatherette and metal accents ensures durability for daily use.

Who the Joyo BA-30 Vibe Cube Black Is Built For

The Joyo BA-30 Vibe Cube Black is aimed at bassists seeking a single amp for bedroom practice, livestreaming and small gigs without lugging a full stack. Home players enjoy silent headphone output and Bluetooth streaming; content creators appreciate the USB-C recording path that removes the need for a separate audio interface. The lightweight build, top handle and option for USB-C power bank operation suit travelling musicians and songwriters. Four-string basses in standard tuning get the most balanced sound from the 4-inch driver and passive radiator.
