JOYO Vibe Cube JOYO-BA-30 WH Bass Combo Amp, 30W, Bluetooth 5.1 + OTG

Set up for a home bass practice session, stream a backing track over Bluetooth and shape your tone right on the amp. The JOYO Vibe Cube BA-30 pairs a 30W output with a 4-inch speaker in a compact, carryable design. Its OTG connection also lets you record directly to a phone or PC.

Practical tips

Use the three-band Bass, Mid and Treble EQ to adjust your sound, then fine-tune the midrange with the dedicated Mid FREQ control, which covers 200Hz–2000Hz. Built-in compression can smooth sharp attacks and bring out quieter fingerstyle notes. If you play an active-preamp bass, the manufacturer recommends avoiding maximum settings on every EQ band, if the signal peaks, lower the Bass EQ and adjust the amp’s gain.

For private practice, connect headphones to the 3.5mm output. To record, connect a phone or PC to the USB-C OTG input and use the independent OTG volume control to set the recording level. Bluetooth 5.1 provides a wireless way to play backing tracks. The amp needs an external power source: use the included adapter for wall power, or a compatible USB-C PD 2.0-or-later power bank rated at 65W or higher with a cable capable of 65W. The power bank is not included.

What you’ll notice day to day

The compact cabinet and top handle make it straightforward to move between a practice spot, desk or recording setup. The 30W output, 4-inch speaker and 113x113mm low-frequency radiator are designed for bass, while the EQ and compression give you hands-on ways to shape your playing sound. For a simple practice arrangement, plug in and play through the speaker or headphones, for a recording workflow, OTG audio goes directly to a phone or PC, avoiding the need for a separate audio interface. Bluetooth playback is useful when you want backing tracks alongside your instrument.

Customer feedback often highlights the amp’s compact size, portability and bass sound, including its mids and lows in small-room practice. Views are more mixed on its power, controls and overall functionality, so these are worth weighing against your intended setup. If recording and practice are both part of your routine, the built-in OTG connection and headphone output bring those tasks together in one small amp.

Should you buy it?

Choose the Vibe Cube BA-30 if you want a portable bass combo for practice, headphone sessions and direct phone or PC recording. Its dedicated bass tone controls, Bluetooth playback and OTG recording make it a practical fit for players who want more than a basic practice amp without adding a separate recording interface to their setup.
