15W Digital Bass Amplifier with 9 Preamp Models

It features 9 professional preamp models:

• 5 classic bass preamps

The FLAT mode provides a flat frequency response, allowing the DC-15B to function as an FRFR-style amp (Full Range, Flat Response), making it ideal for acoustic instruments or multi-effects processors.

Whether you’re dialling in vintage warmth, modern punch or clean acoustic tones, the DC-15B adapts to multiple playing styles and musical settings.

Built-In Looper and 36 Drum Patterns

Creativity is at the core of the DC-15B.

The integrated 30-second looper supports overdubbing, allowing you to layer bass lines and create rich arrangements. Independent track volume control ensures balanced playback while practising or performing.

Looper controls:

• Press the looper switch to start recording

• Blue light indicates playback or when recording reaches 30 seconds

• Double press and hold in playback mode to clear all recordings

In addition, the 36 built-in drum patterns include adjustable tempo and volume controls, giving you a full rhythm section for practice, composition and live performance.

6 Built-In Effects for Tone Shaping

The DC-15B includes 6 high-quality effects for detailed tone control:

Modulation effects:

• Chorus

• Flanger

• Tremolo

• Phaser

Spatial effects:

• Reverb

• Delay

These effects allow you to craft textured, dynamic tones suitable for modern bass playing, ambient layers or creative solo performances.

Included Footswitch for Live Control

The bundled footswitch allows hands-free control so you can focus on playing. It enhances usability during live sessions and makes switching presets or activating features seamless in performance situations.

Bluetooth 5.0 Streaming

With Bluetooth 5.0 connectivity, you can wirelessly connect smartphones, tablets or other devices to stream backing tracks directly through the amplifier.

To activate Bluetooth:

• Long press the BT switch to turn on or off

This makes the DC-15B ideal for rehearsals, jam sessions and learning new material.
