The Cube Street range is virtually synonymous with busking and street performance. We’ll go so far as to wager that there isn’t a popular waterfront or street corner in the world where you won’t see a Cube Street at the feet of the talented musicians entertaining passers-by!

There are two amps in the Cube Street range – the original Cube Street and the Cube Street EX. Which one you choose depends on your needs – are you a solo performer running backing tracks from your phone? Do you use just a single guitar or have you got multiple instruments to plug in? Or do you have several band members performing together?

We’ve compiled some of the key features of both the Cube Street and Cube Street EX to help you figure out which one works for your situation – and there’s also a handy summary table at the end of the article!

  • The lightest and most portable Cube Street
  • 5W power rating punches above its weight with high performance speakers 
  • Input a mic and guitar, with versatile mix of on-board COSM amps and effects
  • 6AA batteries will last 15 hours
  • Common features – tuner, footswitching, 3-band EQ, AC adaptor included

Weighing in at a mere 5.9 kg, the original Cube Street is lightweight and ultra-portable. You can run it for up to 15 hours on just 6x AA batteries, or use the included AC adaptor.

It’s rated at 5W of power but don’t let that fool you – it punches well above its weight through a pair of 6.5 inch high performance speakers!

Crowd ready!

You have a choice of two inputs – one is a combined XLR/TRS which you can plug in a microphone or a line level input like a keyboard or synthesizer; the other is a standard ¼” TRS jack for you to plug your guitar into.

On the Mic channel, you can fine tune your sound with bass/treble controls as well as delay or reverb.

On the Instrument channel, a wide variety of COSM amp models are available, from acoustic simulator to iconic JC clean, all the way up to chunky high gain. These are supported by classic effects types like chorus, phaser, flanger and tremolo, as well as a choice of delay or reverb.

Round off these great features with stereo aux in to run backing tracks from your phone or computer, as well as stereo phones out for silent practice, and it’s clear why the Cube Street is the standard choice for so many street performers across the globe.

But if you need a bit more, read on…


Cube Street Ex Guitar Amp
  • Supports more inputs for busking with multiple instruments or bigger groups 
  • Innovative technology uses 8AA batteries to generate a huge 50W of power
  • Get extended battery life using power saving modes
  • Incorporates two pairs of discrete woofers and tweeters for great full range sound

  • Stand mountable. Stereo link to create powerful mobile PA system
  • Streamlined selection of COSM amps and basic effects
  • Common features – tuner, footswitching, 3-band EQ, AC adaptor included

Cube Street EX takes things to a whole new level, sporting up to 4 inputs and a huge 50W of power to support busking with multiple instruments or bigger groups – or, if you just want to be louder than the busker a few metres down the sidewalk from you!

The versatility of the 4 inputs allows you to amplify almost any configuration of instruments and vocals for street performance, giving you a unique edge on the competition. For example, you might run:

Setup Examples
  1. Keys + vocals + electric guitar
  2. Acoustic guitar + electric guitar + vocals
  3. Electronic drums (in stereo) + electric guitar + vocals
  4. Two vocals + synth (in stereo)

The possibilities are endless!

Sound quality is upgraded over the standard Cube Street by incorporating a stereo pair of 8 inch woofers and dedicated 2 inch tweeters to allow fantastic full range sound reproduction for backing tracks or instruments like electronic drums and synthesizers. With i-CUBE Link and the free CUBE JAM app you can easily control backing tracks from your Apple device, and even record straight to your phone!

A core selection of COSM amps is represented – from acoustic guitar preamp and acoustic simulation to clean/crunch/lead options; as well as a trusty trio of effects – reverb, delay and chorus.

The innovative power optimisation technology allows 8x AA batteries to power the EX for up to 20 hours on ECO mode (10W) – with 15 hours available on NORM mode (25W) and 5 hours on MAX mode (50W).

If 50W of power isn’t enough, you can even stereo link another Cube Street EX to form a mighty but mini portable PA system – mountable on speaker stands for maximum sound dispersion. In this configuration you can run up to EIGHT simultaneous inputs – no need to shell out for a separate mixing desk.

Considering the huge bump in power, increased versatility, and great quality of sound reproduction, the EX is still extremely portable at 7.4kg!
