BOSS RT-20 ROTARY ENSEMBLE.
From the Beatles to Jeff Beck, Santana to Stevie Ray, many guitar
greats have incorporated the rotary speaker into their rigs. With this
in mind BOSS proudly presents the RT-20 Rotary Sound Processor.
Employing COSM®-modeling technology, the RT-20 authentically reproduces
classic rotary-speaker sounds. It offers adjustable Rise Time, Horn and
Bass speed, Overdrive, and more. And not just for classic twirl, the
RT-20 can be used to create unique overdrive and pulsating effects as
well. This pedal sounds amazing, and offers a stunning graphical view
of the virtual rotors on its built-in display.
- Authentic rotary speaker sounds via COSM technology
- Slow/Fast transition time is adjustable from gradual to rapid change; optional Expression pedal can control speed in real time
- Onboard Overdrive effects
- Adjustable mix balance between Treble Rotor and Bass Rotor
- 4 types of sounds, from standard rotary speaker effects to rock-oriented tones, UNI-V, and more
- Guitar/Keyboard switch
- Dazzling virtual-rotor display
COSM Technology
Years
of intensive research and development have made Roland and BOSS world
leaders in modeling technology. Roland’s breakthrough Composite Object
Sound Modeling (COSM) uses the advantages of multiple modeling methods,
and succeeds in accurately emulating existing sounds as well as
producing sounds that have never before been created. With the RT-20,
COSM is used to simulate classic rotary characteristics, and beyond.
The virtual horn and bass speaker can be independently adjusted, while
the RT-20’s unique graphic display provides a realtime view of the
rotation pattern and speed.
Connections
Guitars
and keyboards alike can be plugged into the RT-20; use the Drive Type
switch to optimize the effects for guitar or keyboard. Surround your
listeners in animated sound with the RT-20’s dual outputs, which enable
true stereo effects. Add color by adding an Expression pedal (such as
the new BOSS FV-500H/FV-500L, optional), which lets you control
parameters such as rotation speed seamlessly from slow to fast in real
time. The RT-20’s phone jack is handy for private practice and
experimentation.
Virtual Rotor Display
Thanks
to its stunning visual display, the RT-20 might be the most
eye-catching pedal in BOSS history. The spinning lights don’t just look
cool, they also show the audio-rotation characteristics of the RT-20 in
real time. The center of the display, illuminated in red light,
represents the virtual horn. The outside ring, illuminated in blue,
displays the rotation of the virtual bass speaker. It’s attractive and
informative!
