A Practice and Performance Powerhouse

The BOSS Dual Cube Bass LX brings endless utility and punchy stereo bass tone to the renowned Cube series! This 2 x 5-inch speaker amplifier pushes 10-watts for a robust sound that belies its compact size, offering 5 versatile preamp settings to cover everything from ultra-flat slap tones to modern aggression. Next, seven built-in effects, a 3-band EQ, and the Dual Cube Bass LX Editor app allow you to finely sculpt and adjust every parameter of your sound — you can even save your favorite creations for later using the 15 memory presets. When it comes time to sharpen up your chops, the Rhythm Guide provides a diverse range of percussion styles and patterns to serve as your personal backing track. The Dual Cube Bass LX’s diverse range of connectivity options make it equally suited for street performance, dialed-back jams, recording, or livestreams, making it perhaps the most flexible Cube yet! Did we mention that it offers both an AC adapter and AA battery functionality? From the stage to the desk, the BOSS Dual Cube Bass LX is all but guaranteed to maximize the potential of your practice sessions, performances, and recordings.

Designed for portability

Portability is a key component across the entire Cube range, so it’s no surprise that the Dual Cube Bass LX boasts a sleek, compact form factor. However, tucked away in its unassuming size is a powerful 2 x 5-inch custom speaker design, pushing 10 watts to effortlessly cover everything from street performances to small jam sessions. What’s more, the Dual Cube Bass LX offers both an AC adapter for at-home playing and AA battery operation (eight) for complete sonic freedom.

Cover endless sonic ground

The Dual Cube Bass LX’s five preamp settings cover a serious amount of sonic ground, providing uncolored sounds for slappers and studio musicians, crunchy aggression for modern rock and metal players, and smooth old-school tones for vintage-style thump. These preamps are precision-tuned by BOSS for natural response and tone, but that’s just the beginning of the Dual Cube Bass LX's mighty versatility; a host of bass effects are built right into this amp — compression, drive, chorus, flanger, you name it. Plus, the Dual Cube Bass LX editor provides extensive customization tools to perfectly tune your effects to taste. Finally, 15 memory presets (three for each preamp type) are available to instantly access your favorite amp and pedal settings.

Limitless connectivity

Need an amp for the stage? What about studio recording? Streaming a performance of your latest track? The BOSS Dual Cube Bass LX boasts a wide range of connectivity options to meet the needs of any musical task. Hooking your Dual Cube Bass LX to a stage PA is a breeze, thanks to the stereo XLR line-out, which allows you to tackle any audience size with ease. Moreover, the USB/i-Cube link connections allow for effortless home recording and play-along practice to your favorite tracks. You can even capture your voice via headphone mic to send both your voice and bass signal to your livestream!

You’ve got rhythm

Rhythm is a vital skill for any bass player — somebody’s gotta keep the band in time! If you’re looking to practice playing in the pocket, the Dual Cube Bass LX’s Rhythm Guide is purpose built to optimize your timing training. Nine distinct rhythm types are available in styles ranging from a basic metronome to Latin to rock, each with three dedicated patterns to find your groove. Hop onto the Dual Cube Bass LX Editor to access up to 91 rhythm variations, and you can even save your favorites directly to the amp. While these rhythms are an excellent tool to fully immerse yourself in a practice session, Sweetwater bassists find that they also serve as a capable backing track for street performers and quiet jam sessions.

Great Amp for Cello - See Attached Video

See attached video (the amp is behind me). For electric cello, this amp kicks it! My wife and I recorded Pachelbel's Canon :: I used the looper to record the guitar arpeggios, then played the cello part on top of that. You will want to download the free software to set the looper to 90secs (default is only 45 secs).

An everything practice package!!

I have this things big brother in the basement if I really want to shake the walls. Truth be told….this thing can do a couple things big bro can't. First, this can double as a Bluetooth speaker and play music or whatever you're listening to on your device (buy the adapter). Second, it has built in drum or metronome backing in multiple genres. Lastly, there's a looper that will work with an optional pedal that I don't have but also don't need at this time. Thanks to this little gem, I now have a bass and amp in everywhere I usually am to take away the excuses! Special thanks to Richard Granger for his assistance and friendliness in making this purchase.
Rated 5/5

Almost a "must have"

Since they've apparently discontinued the 4 x 5", and if you don't already have that model (as I do), this is almost a "must have" IMO; for practice (incl. quieter rehearsals w/ full bad/partners) and even busking (w/ AcBassGuit or even regular guitar), this thing is fantastic. The sound is amazing, the models/settings are so on-point, and for private practice, the built-in drum rhythms are beyond-the-pall surprising as to how great they are (great sounding, and useful/inspiring) compared to a simple metronome. For this lower price, I'm tempted to get this as well--they are that useful, versatile, well-built, easy to use, and fantastic sounding.
Rated 4.5/5

Power in a small

This is a very powerful and useful bass amp all in a very compact box. It sounds terrific as well.
Rated 4/5

Jack of all trades

There's a lot of value in this amp. The range of tone is good for an amp this size. Since it's portable that will mean one less pedal. The drum machine is nice for practice and allows for some variation in style, and you can punch in tempo. The looper is okay, it won't let you record a full 12 bar blues at a lower BPM which is important for noodling around as a bassist. The overdubbing is nice.

The amp has a long lifespan on battery life, I had to pick up some rechargeable double-A's for it. You get around 8 hours on a charge. Would be nice if it were a rechargeable battery.

It's a very feature-rich amp, sounds good, and for a portable amp it has a lot of value. But charging and looping could be better
