It’s extraordinary to think that the first Roland Cube guitar amp dates as far as back as 1978, and since then there’s been over 50 versions, each promising high-quality tones with unparalleled portability for the guitarist on the move. 

In 2021, with the introduction of the Cube Street II, the series was switched over to the Boss line – a sensible consideration given the brand’s guitar-centric legacy. The newest addition to the family is the Dual Cube LX, which offers more controls and features than any of its predecessors in a desktop amp format.

One of the most popular additions to the more expensive Cube Street II was its 45-second looper system, so busking/one-person-band types will be pleased to see that included here, though it requires an additional footswitch such as the Boss FS-6 – there are no onboard buttons to start and stop loops. 

The footswitch input found at the back is also capable of navigating through the 27 memory presets – three for each of the seven amp types, plus another three for the Microphone and Stereo In channels.

Speaking of amp types, there’s a lot on offer: from a highly realistic Acoustic Simulator, Roland Jazz Chorus setting, Fender-esque US Clean and Vox-ish Brit Combo before you get to the more metallic options like Hi-Gain Stack, Metal Stack and the infinitely scooped Extreme. 

It would be fair to say, as often with amps of this nature, it’s the ultra-low gain and high-gain tones that seem to work best – those opting for crystal cleans or heavily saturated levels of distortion will get the most out of the Dual Cube LX. 

Convincing edge-of-breakup sounds for SRV-style blues will present more of a challenge, but then again it’s worth noting only a small handful of valve amps are capable of authentically replicating one of the most highly sought-after and exponentially lavish tones in guitar history.

As for effects, there are options for chorus, flanger, phaser, tremolo and heavy octave, and another dial for reverbs and delay with a tap tempo control – all of which perform to the dependably high levels Boss are renowned for, especially with the extra width provided by the stereo speakers. 

Those looking to deep dive even further will be pleased to find that the USB socket at the rear allows for software editing and direct recording. 

Though it’s plenty loud for its size, there’s also a stereo line out at the back, which could come in handy for performing in larger spaces where there’s an option to go through a mixing desk and PA.

With some stiff competition in recent years from the likes of Positive Grid and Yamaha, it’s clear Boss has been paying attention to what features have been most popular on Cube amps of the past and evolving the range in the right direction while also keeping affordability in mind.
