Every detail of our cabinets, speakers, and components

Portable & Battery-Powered
Enjoy music anywhere, anytime. Go mobile with Roland’s
lightweight, battery-powered amps!
COSM, the ultimate in amp-modeling technology, was
developed by carefully studying vintage masterpiece
amplifiers. Our engineers meticulously verified the
characteristics of various components and the behavior
of circuits from coveted guitar and bass amps. Even
speaker and cabinet characteristics have been
precisely modeled in COSM to reproduce the exact
playing feel and nuances of the original amps.
COSM modeling is featured in a wide range of amps,
from our professional stage combos to compact
CUBES that you can enjoy in a bedroom. COSM
connects you to the DNA of masterpiece amps, letting
you experience the heart and soul of a classic.
From the ongoing evolution of COSM comes Roland’s
original Progressive Amp*, which exceeds the
boundaries of existing amp modeling schemes.
This technology lets a single amp deliver a wide range
of sounds that are simply impossible to create on
existing amps.
* Equipped on the GA-212 and GA-112
GA
GA-series stage amps provide high-caliber sound, playability, and
rock-solid construction that top professionals around the world
demand. Colorful, bold, and revolutionary, these amps are
powered by state-of-the-art COSM technology, and earn the title of
“flagships of the fleet”.
JC
The Jazz Chorus JC series represents the origin of Roland amps.
When the JC-120 debuted in 1975, it was heralded as a solid-state
marvel of unique technology and sound. Today, decades later,
the JC-120 is still coveted by guitarists around the world.
CUBE
Travel friendly and filled with features, the CUBE series packs
state-of-the-art amp technology and functionality into compact
cabinets. These high-performance mobile amps are great for
bedrooms, practice studios, outdoor gigs, and beyond.
CM
The CUBE Monitor CM series is optimal for monitoring your music
during performance or in music-production environments. With their
high-fidelity 2.1-channel design, the CM-220 and CM-110 deliver
wide-range sound reproduction. The CM-30 is a best-selling monitor
amp that supports a multitude of applications.
AC
Since it was launched in 1995, the Acoustic Chorus AC series has
become the standard amp for acoustic guitars. This amp series was
specially designed for acoustic instruments, meticulously handing the
warmth and pure sound that acoustic guitars are known for.
BA
The BA series supports a variety of inputs, including instruments,
microphones, and various audio gear. With support for battery power
and an anti-feedback function for preventing howling, these portable
amps can be used for a wide variety of applications.
The cabinet also represents Roland’s audio
technologies and know-how. All elements of the
cabinet — including material, board thickness, and
construction — have been designed to deliver the
ultimate in sound quality and durability. The CUBE XL
series, for example, employs a baffle made of
ultra-sturdy direct-joint construction and a closed back
to improve deep frequency response. Additionally,
every element — from protectors, metal grills, and
rubber feet — have been designed to deliver the
ultimate sound and strength.
All Roland amps are equipped with high-fidelity
custom speakers that have passed stringent durability
tests. With meticulous attention given to the choice
of speaker material, these speakers are designed to
maximize every ounce of the amp’s potential.
GA series speakers are equipped with powerful
magnetic circuitry that translates every detail, from
subtle picking nuances to dynamic low end.
The tweeter used in the CM-220/CM-110 amps
consists of a silk dome diaphragm and aluminum
voice coil. The woofers on these amps use an
aluminum-deposited fiber cone. As a result, these
speakers are built to handle every detail of
the source signal.
Our pursuit of perfect portability covers all bases —
from cabinets and speakers to the smallest internal
components — without compromising sound quality
and durability. Thanks to their travel-friendly design,
including battery-power capability and convenient
carrying handles, these units are ready for the road.
Roland’s battery-powered amps such as MOBILE BA,
MOBILE CUBE or BA-55 etc. deliver powerful sound
that defies their diminutive body size. Carry them
anywhere! With battery power support, these amps
let you take your show on the road, even to outdoor
locations where no power outlet is available.
In order to ensure battery availability and to achieve
a lightweight cabinet, all Roland battery-ready amps
accommodate size AA batteries. With a high-efficiency
design based on Roland’s state-of-the-art technologies,
these amps allow extended playing times on battery
power.
