Stage Sound at Home
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.

Please register this product online to establish the date of purchase (not a requirement for warranty service).
To exercise your rights under this Warranty as a purchaser, you must ship this product in appropriate packaging at your expense (insurance is recommended), together with proof of purchase, to Roland Corporation U.S., or to such other address as may be instructed by Roland Corporation U.S. (This shipping requirement shall not apply to those Roland products covered by in-home warranties). You should submit a new service request to obtain a Return Authorization number for the returned product. Any products shipped to Roland Corporation U.S. without a Return Authorization number shall be refused.
Roland Corporation U.S. will repair or replace this product at its sole option at no charge to you for parts or for labor within the warranty period; provided, however, that Roland Corporation U.S. reserves the right to determine whether the product is 'defective' for purposes of this Limited Warranty. This Warranty does not apply to damage to this product that occurred as a result of abuse or misuse, abnormal service or handling, battery leakage or failure, damage which may have been caused either directly or indirectly by another product, or if the product has been altered or modified in any way, or if the damage was caused by repairs or service provided or attempted by anyone other than Roland Corporation U.S. or a Roland Authorized Service Center.
In no event shall Roland Corporation U.S. be liable for any indirect, incidental, collateral, exemplary, punitive, consequential or special damages or losses arising out of your purchase of products and/or out of this warranty, including without limitation, loss of use, profits, goodwill or savings or loss of data, music, electronic files, or programs that may have been stored by a user of the product even if Roland Corporation U.S. has been advised of the possibility of such damages or claims. Some states do not allow the exclusion or limitation of incidental, punitive, or consequential damages, so the above limitation or exclusion may not apply to you.
Where applicable, if you qualify as a 'consumer' under the Magnuson-Moss Warranty Act, then you shall be entitled to any implied warranties allowed by law for the period of the Limited Warranty as set forth above. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. Except as stated above, the foregoing warranties are in lieu of all other conditions or warranties, express, implied or statutory, including without limitation, an implied condition or warranty of merchantability or fitness for a particular purpose and of any other warranty obligation on the part of Roland Corporation U.S.
