Roland CUBE-20GX Guitar Amplifier - iPhone Connectivity - The starter amp market can get you down. Tinny tones, puny power, drab features, dull styling: surely there has to be a first-step amp that goes further? Meet the new CUBE-20GX. Compact but potent, with a 20-watt output and 8-inch custom-designed speaker, it’s a practical combo that builds on the market-leading features and reliability of the original CUBE range. Built for the player still finding their signature tone, the 20GX is a versatile choice, with three footswitchable channels, a variety of pro effects and amp models, combined with the option to store bespoke tones. Reflecting the rise of home-based recording, the i-CUBE LINK option provides a simple on-board audio interface, connecting with iOS devices like the Apple iPhone, iPad and iPod Touch for mobile recording and practice.

  • 20-watt guitar amp with custom-designed 8-inch speaker
  • Three channels: JC CLEAN, LEAD (six different types), and SOLO
  • SOLO channel is fully programmable, allowing you to save and recall JC CLEAN or LEAD sound type plus EQ and effects settings
  • Three independent effects sections: EFX (five types), DELAY, and REVERB
  • Hands-free channel switching with optional BOSS FS-5U or FS-6 footswitches
  • i-CUBE LINK jack provides simple audio interfacing with iPhone, iPad, and iPod touch (interface cable included)
  • Free CUBE JAM app for iOS plays songs and minus-one jam tracks, and lets you record the CUBE-20GX’s tones along with music playback
  • Three-band EQ; built-in chromatic/manual tuner
  • RECORDING OUT/PHONES jack for silent practice and direct recording

Unlock Your Sound

Some entry-level amps commit players to a ‘one-size-fits-all’ sound. With its three independent channels and wide selection of great guitar tones, the CUBE-20GX is ready for any style you throw at it. The JC CLEAN channel delivers the clean tone of Roland’s iconic JC-120, while on the versatile LEAD channel, you’ll find six additional tones ranging from an acoustic guitar simulator to the organic crunch of ‘Overdrive’ and the heavy gain of ‘Extreme’. The SOLO channel is fully programmable, allowing you to store all settings from either the JC CLEAN or LEAD channel, complete with EQ and effects settings. Channels can be selected from the front panel or remotely via optional BOSS FS-5U or FS-6 footswitches.
No Need For Pedals Or Tuners

When you’re starting out, you might not have money to burn on pricey effects pedals. With the CUBE-20GX, that’s no problem, with three separate onboard effects sections supplying pro-quality processing, and intuitive controls meaning you can dial up great tones with ease. The EFX section includes five stompbox-type effects, while the dedicated DELAY section provides two different flavours, and REVERB offers a choice between vintage spring emulation and studio-style plate. The CUBE-20GX also has a chromatic/manual tuner, built into the amp to ensure you’ll never be left hunting for pitch pipes while the crowd turns nasty.
i-CUBE LINK: A Simple Way To Record

More than ‘just’ a great-sounding guitar amp, the new CUBE-20GX features Roland’s i-CUBE LINK interface, allowing two-way connectivity and easy recording with an iPhone, iPad or iPod Touch. Unlike some bulky iOS interfaces, i-CUBE LINK simply connects to your device’s audio jack with the included cable, enabling you to play along with music tracks and send studio-quality bespoke amp tones direct to the recording app of your choice. The i-CUBE LINK jack can also be used as a simple stereo input, connecting to most audio devices and turning the CUBE-20GX amp into a high-quality music playback system.
Free CUBE JAM App: Get Better Faster

Available free from the App Store, the Roland CUBE JAM app turns your iOS device into a command centre for jamming, recording and learning. Using the i-CUBE Link, you can play back your favourite songs as minus-one tracks and jam along for hours using the 20GX’s great tones. In addition, CUBE JAM works like a virtual studio, letting you record, perfect the mix, then export it to a 16-bit, 44.1 kHz WAV file. CUBE JAM also features powerful tools for practice, including independent speed and pitch adjustment of audio playback, plus Center Cancel to remove solos and create your own jam tracks. And that’s just the start…
