For over four decades, CUBE amplifiers have brought exceptional value to musicians everywhere, offering great sound and versatile features in portable, go-everywhere designs. The DUAL CUBE BASS LX is the most advanced compact CUBE bass amp yet, filled with evolved BOSS technologies for the ultimate home practice experience. This thunder box punches well above its size, delivering rich, full sound and a host of fun rhythm patterns to groove with. A generous array of connectivity options are also included, extending its range to performing, recording, and many other applications.

With its custom stereo speaker system and advanced cabinet design, the DUAL CUBE BASS LX delivers big, refined tones that you won't believe are coming from such a small amp. Five different preamp types are available, offering uncoloured sounds for studio and slap playing, vintage sounds for classic styles, and aggressive modern tones for heavy genres. With natural feel and organic response honed with decades of BOSS amp development, you have an endlessly inspiring platform to hone skills and explore new techniques.

The DUAL CUBE BASS LX features a variety of bass-tuned effects, including many with expansive stereo sound. Shape your core tone with compression or drive, add colour with touch wah, flanger, or chorus, and bring in spatial depth with delay or reverb. Each amp type includes three user memories, allowing you to store gain, EQ, and effect setups for quick recall. The DUAL CUBE BASS LX Editor lets you dive even deeper, providing access to effect variations and detailed parameter tweaks from your Mac or Windows computer.
