Simple Operation—Works Like a

processors, lets you make changes to tones directly.
High-Quality Sounds Through COSM

Overdrive/Distortion, which make full use of COSM
technology, you can perform with a variety of powerful
effects, from classic vintage sounds to new and original
Multi-Function Expression Pedal

gives you control over six different specialized pedal
effects. It can also be switched for use as a volume
You can store up to 24 original tones you have created.
You can also use the pedals in “Memory mode” to call
up stored tones instantly.
AUX IN Jack
The AUX IN jack makes it easy to practice along with
CDs, MDs, and other input.
The ME-50B can be powered in two ways, with (6) AA
batteries or by using the AC adaptor (optional).
COSM (Composite Object Sound Modeling)
Composite Object Sound Modeling (COSM) is Roland’s
innovative and powerful sound modeling technology.
COSM analyzes the many factors that make up the
original sound, such as the electrical and physical
characteristics of the original, and then produces a
digital model that can reproduce the same sound.
