JOYO VIBE CUBE BA-30 30w Bass Amp Portable Combo Amplifier with Bluetooth 5.1 and OTG Recording

The JOYO VIBE CUBE BA-30 is a compact 30W bass combo amplifier designed for serious low-end performance in a portable format. Built for practice, livestreaming, rehearsals and small solo gigs, this 4 inch bass amp delivers punchy lows, clear mids and articulate highs thanks to its full-range speaker and dedicated bass radiator system.

Finished in classic black and weighing just 2.7kg, the BA-30 is ideal for bassists who need professional tone in a lightweight, easy-to-carry design.

30W Dynamic Bass Power with Enhanced Low-End Response

At the heart of the VIBE CUBE BA-30 is a 4 inch / 30W full-range speaker paired with a 113 x 113mm low-frequency radiator. This combination enhances low-end depth while maintaining clarity across the mid and high frequencies.

The result is a natural, balanced bass tone with tight punch and definition – perfect for electric bass, double bass and even low-register guitar applications. Whether you are practising at home or playing a small venue, the 30W rated power provides strong projection without losing detail.

Precision 3-Band EQ with MID Frequency Control

The JOYO BA-30 features a powerful tone-shaping section designed specifically for bass:

• Bass control

• Mid control

• Treble control

• MID FREQ selector (200Hz–2000Hz)

The adjustable MID FREQ knob allows you to pinpoint critical frequency ranges, helping you cut through a mix, reduce muddiness or highlight fingerstyle nuances. This makes it especially useful for different playing styles and genres.

Built-in Compression for Smooth, Controlled Tone

An integrated compressor smooths sharp attack transients and enhances subtle playing dynamics. It helps even out volume differences between aggressive picking and softer passages, giving you a more polished and professional sound at any level.

Pro tip: For active preamp basses, avoid maxing all EQ bands at once. If the signal peaks, reduce the bass EQ and adjust the gain. Engaging the compressor can help achieve a smoother, more controlled response.

Bluetooth 5.1 Streaming for Backing Tracks

With Bluetooth 5.1 connectivity, the VIBE CUBE BA-30 allows you to stream high-quality backing tracks wirelessly from your phone or other compatible devices. The connection is stable and low-latency, ideal for rehearsals, practice sessions or casual jams.

To activate Bluetooth, simply press the Bass knob to enter pairing mode.

OTG Direct Recording via USB-C

The BA-30 doubles as a compact recording interface thanks to its OTG Type-C USB port. Connect directly to your smartphone or computer for recording demos, livestreams or social media content without needing an external audio interface.

A dedicated OTG volume control lets you adjust recording levels independently from the main output, ensuring clean signal capture.

Silent Practice with Headphone Output

For late-night sessions or private rehearsal, the 3.5mm headphone output delivers full-range monitoring with a 32Ω headphone impedance. This makes the BA-30 ideal for home practice without disturbing others.

Portable Design with Dual Power Options

The JOYO VIBE CUBE BA-30 is designed for maximum portability while maintaining professional performance:

• Weight: 2.7kg (approx. 6 lb)

• Dimensions: 7.2 x 6.5 x 8.5 inches

• Durable ABS, leatherette and metal construction

• Reinforced internal bracing

• Sturdy top carry handle

Important: The BA-30 does not have an internal battery and requires continuous external power.

Power options include:

• Included AC adapter (AC 100–240V, DC 20V/2A, 40W, centre negative)

• Compatible USB-C power bank (must support PD 2.0, 3.0 or later with 65W+ output and a 65W high-current USB-C cable)
