Groundbreaking Stage Amps with Original Tone

The GA-212 stage amplification system meets the rigorous demands of performing guitarists. Unlike modeling amps that set out to recreate the sound of multiple vintage classics, the GA-212 leverages Roland’s renowned COSM technology to create newly-voiced amplifier with versatile, expressive tones and simple, intuitive operation. It delivers an organic playing experience characteristic of top-level tube designs, with all the advantages that modern digital processing brings, including memory, low noise, and more. From the arena to the club, the GA-212 delivers world-class power and tone.

  • - 200-watt amp with two 12" speakers
  • - Original COSM amp model (Progressive Amp) with incredible feel, attack, natural compression, and sustain
  • - Morph through clean to super-extreme tones with the DRIVE knob and BOOST button
  • - Intuitive operation with simple, fast-access structure; two volume controls, three tone controls, presence, and reverb
  • - Smart Channel memorizes the current position of knobs in all four channels without programming or saving
  • - LEDs in the knobs show current settings in any channel, great for dark stages

Progressive Amp

With this single, cutting-edge amplifier, you can create a landscape of unique tone — from clean to crushing — that’s impossible with traditional amps. One of the GA’s secret weapons is Progressive Amp, which lets you sweep distortion amount and tonal character along a smooth curve. Adding another dimension to this process is the Sound Indicator, which displays the level of distortion in a range of colors. This provides an intuitive, visual view of the sound in real time.

Instant Access

No matter what sound you’re going for, the GA-212 makes it fast and easy to find with only two volumes knobs, three tone-control knobs, and presence, and reverb effects to navigate. From your mind to your fingers, the GA-212 inspires fast workflow and fluid performance.

Intuitive control with Smart Channel

The GA's innovative Smart Channel feature scans and saves your panel settings automatically, and you can recall all four channels of settings with a single button push. No mystery, no confusion — the bright LED knobs clearly indicate the positions of each parameter, visually confirming the settings even on dark stages.

Signature Style

The GA-212 is the brainchild of Roland and BOSS R&D, a world-leading force in cutting-edge sound. It features the latest advancements in tone tech, yet provide easy operation with signature styling. You'll turn heads with these attractive, road-tough amps, which look as cool as they sound.

Stack your amps for extraordinary power!

The GA series lets you stack amps through its Link connector — great for guitarists who are looking for even higher decibel levels. Connect two GA-212s for up to 400W of power!

* Up to two units can be stacked. Do not stack three or more units.

Control channel switching and other functions via foot controller

You can easily switch channels while you play using the customdesigned GA-FC foot controller (sold separately). You can also use the GA-FC to control the two independent effects loops, or to turn reverb on and off. For the ultimate in foot control, you can connect two expression pedals to change the drive and volume levels independently.
