JOYO Vibe Cube BA-30 JOYO-BA-30 WH 30W Bass Combo Amp with Bluetooth 5.1 & OTG

Some bassists need a simple amp for playing at home, others want playback and recording tools built in. The JOYO Vibe Cube BA-30 brings those tasks together in a compact 30W combo. Shape your tone, play along with Bluetooth audio, or connect for OTG recording.

What stands out

A 4-inch full-range speaker and 113 x 113 mm low-frequency radiator pair with 30W output for a bass-focused practice setup. The three-band Bass, Mid, and Treble EQ gives you direct tone controls, while the separate Mid FREQ control lets you target frequencies from 200Hz to 2,000Hz. Built-in compression helps smooth the attack and bring quieter notes forward as you play.

Bluetooth 5.1 lets you stream backing tracks from a compatible device, so you can play along without routing that audio through a separate playback setup. For recording, the USB-C OTG connection links the amp directly to a phone or PC, with an independent OTG volume control for the recording level. Customers often highlight its tone, compact size, Bluetooth playback, and usefulness for home practice, opinions about its volume vary.

Who it’s for

The Vibe Cube suits bassists who want a dedicated practice amp with more than basic amplification. Use Bluetooth to play along with tracks, then connect through USB-C OTG to capture a demo or send audio to a phone or PC for a livestream. The headphone output provides a way to practice privately, while the EQ and compressor give you practical controls for adjusting your sound at home or while working on song ideas.

This setup favors an all-in-one practice and recording workflow over an amp focused only on instrument amplification. Its carry handle and 2.7kg weight also make it easier to move between a desk, practice space, and recording area.

Practical questions

Can I practice with headphones? Yes. Connect headphones to the 3.5mm jack for private practice with full-range sound.

How do I record through OTG? Connect the amp’s USB-C OTG port to a compatible phone or PC. The dedicated OTG volume control adjusts the recording level independently.

Can I use it away from a wall outlet? The amp needs continuous external power and has no internal battery. For portable use, connect a power bank that supports USB-C PD 2.0, 3.0, or later at 65W or higher, using a cable rated for 65W or higher.

When it makes sense

Choose the JOYO Vibe Cube BA-30 when your bass practice calls for hands-on EQ, Bluetooth backing tracks, and a direct OTG recording path in one portable combo. It’s particularly suited to home practice, working through song ideas, and creating recordings or livestream audio without adding a separate interface to the setup.
