Building on the top-level tone and rock-solid reliability that's made the CUBE name famous, the all-new CUBE-GX series turns up the heat with even more versatile operation and connectivity for Apple's iPhone, iPad and iPod touch. Small yet mighty, the CUBE-20GX is a potent tone machine with features and performance that easily make it the best value in its class. Three footswitchable channels include JC CLEAN, LEAD, and a fully programmable SOLO channel, with built-in sound enhancement on tap in three independent effects sections. i-CUBE LINK turns the CUBE-20GX into a powerhouse for practice and mobile recording, providing a simple onboard audio interface for working with music apps on your favorite iOS devices.

With three independent channels and a wide selection of great guitar tones, the CUBE-20GX is ready for playing any musical style. The JC CLEAN channel provides the clean sound of Roland's famous JC-120, while the versatile LEAD channel offers six tones to choose from. Included are distortion sounds from warm OVERDRIVE to the massive gain of EXTREME, plus a cool acoustic guitar simulator. The SOLO channel is fully programmable, allowing you to store all settings from either the JC CLEAN or LEAD channel, along with EQ and effects choices. Channels can be selected from the front panel or remotely via optional BOSS FS-5U or FS-6 footswitches.

Three separate effects sections supply pro guitar processing right onboard the CUBE-20GX, with simple controls for dialing up great tones with ease. The EFX section offers five stompbox-type effects, while the dedicated DELAY section provides two different delay types. REVERB is included as well, with your choice of vintage spring emulation or a studio-style plate. The CUBE-20GX also features a chromatic/manual tuner, conveniently built right into the amp!

Onboard the CUBE-20GX is Roland's innovative i-CUBE LINK interface, which lets you integrate with your iPhone, iPad, or iPod touch using a real guitar amp with great tone. Unlike typical bulky and inconvenient iOS guitar interfaces, i-CUBE LINK connects to your device's audio jack quickly and simply with the included cable, providing two-way communication with your favorite music apps. With i-CUBE LINK, you can play along with music tracks and send studio-quality guitar tones with effects straight into the recording app of your choice. The versatile i-CUBE LINK jack can also be used as a simple stereo input, enabling you to plug in nearly any music player or audio device and play it through the CUBE-20GX.

Available for free from the App Store, the Roland CUBE JAM app turns your iOS device into a fun command center for jamming, recording, and learning. Play back commercial songs and minus-one tracks through the CUBE-20GX via i-CUBE LINK and riff along for hours with the amp's great tones. CUBE JAM also records audio through the i-CUBE LINK connection, letting you capture your jams with a single touch. After recording, you can adjust the volume of your guitar and backing music independently in the app, then export your mix to a 16-bit, 44.1kHz WAV file. CUBE JAM also includes powerful tools for music practice, including independent speed and pitch adjustment of audio playback, Center Cancel to remove solos and create your own jam tracks, and more.

Amazing what you get in a $200 Amp!

Comments about Roland CUBE-20GX 20W 1x8 Guitar Combo Amp:

I've been away from guitar for almost 20 years, so when I looked around, watched some videos and read a few reviews I thought the Cube 20GX would be a solid choice for a rocker in their forties who needed a solid, versatile amp for practicing in the house. The 20GX has far exceeded my expectations. Pro: The clean channel and acoustic sim setting will make your electric sound like a big hollow bodied acoustic. The Effects are solid and varied. While the number of different tones and sounds you can get out of the lead channel and various COSM settings is impressive. The ability to have a tube sound in a small amp like this is astounding and Roland's sound modeling gets major kudos here. The built-in tuner has two modes and having the ability to use headphones is a big plus. Did I mention that for a 20 watt amp this thing cranks! Way more output than I'll ever need for my house! The controls are straight-forward and the manual is good, even showing a nice variety of baseline settings. Cons: Roland included an i-link input for using iphones and the Roland "CubeJam" app... IMO... it's a MAJOR Mistake to not include an app for Android Devices, as I, and many others are not and will never be Apple users. Roland claims through their website this feature will be coming in the future for Andriod users but no ETA on that. If your an iphone user great, if not, major feature on this amp is DOA. Summary: If your into classic rock or metal, this amp is right up your alley and for $200 it fits in most people's budgets. It's solidly built, eay to get good sound from and offers a wide array of effects, and tones. A 9 out of 10 only because of the lack of Android support for a heavily touted feature.
