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 uncolored 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.

Find Your Voice

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 color 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.

Get in the Groove

Make your practice sessions more fun and productive with the powerful onboard Rhythm Guide. There are nine rhythm types with three pattern variations each, spanning from a basic metronome to realistic drum grooves in rock, jazz, metal, Latin, and other styles. Using the DUAL CUBE BASS LX Editor, you can explore a total of 91 rhythm variations and save your favorites in the amp. With the high-performance stereo speakers, rhythms and backing music are presented in full-range detail for a rich, immersive experience.

Beyond the Bedroom

Thanks to its ultra-flexible connectivity, the DUAL CUBE BASS LX goes far beyond the capabilities of other compact amps. Use the stereo XLR line output to directly connect to a PA system and perform on stage. Or capture mix-ready sounds in music software on a computer or mobile device via USB or i-CUBE-Link. If you like to livestream, you can capture your voice with a headphones mic and send it to the USB and i-CUBE Link outputs along with your bass sound. And with the ability to use AC or battery power, you can play absolutely anywhere.

Expand Your Possibilities

With optional FS-series footswitches, you can operate the Rhythm Guide hands free and unlock access to the onboard looper to create layered performances. And by connecting the optional Bluetooth® Audio MIDI Dual Adaptor, you can go even further with a smartphone or tablet. Wirelessly stream music from your device and jam along, or use the iOS/Android version of the DUAL CUBE BASS LX Editor to tweak functions remotely. Or pair the EV-1-WL Wireless MIDI Expression Pedal for cable-free operation of wah and volume.
