Product Description

The Boss RT20 Rotary Ensemble Pedal, the New Standard in Rotary Speaker Simulation.
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 RT20 Rotary Sound Processor. Employing COSM-modeling technology, the RT20 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 RT20 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.

Boss RT20 Features

  • 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; Rotary speaker effects, 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 RT20, COSM is used to simulate classic rotary characteristics, and beyond. The virtual horn and bass speaker can be independently adjusted, while the RT20's unique graphic display provides a realtime view of the rotation pattern and speed.

Connections
Guitars and keyboards alike can be plugged into the RT20; use the Drive Type switch to optimize the effects for guitar or keyboard. Surround your listeners in animated sound with the RT20's dual outputs, which enable true stereo effects. Add color by adding an Expression pedal (such as the new BOSS FV500H/FV500L, optional), which lets you control parameters such as rotation speed seamlessly from slow to fast in real time. The RT20's phone jack is handy for private practice and experimentation.

Virtual Rotor Display
Thanks to its stunning visual display, the RT20 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 RT20 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!

Now my keyboard has organs that really rock out!
What is your opinion of this product?
It's pleasing to the ears. I love the added sound that the BossRT20 gives to my keyboard playing. I have depth, warmth and added chilling highs to the horns effect of the Balance knob. Creativity is your only friend with this great two pedal ensemble module.

Its Awesome and worth the money
It is sturdy and well made. Should last for a while. Well built but not heavy at all
I have only had it for a week now so can't really comment yet on this. It seems that it will last for a long time (I hope).
Your general opinion of this product.
I love it. I use it with my Roland Juno D keyboard. While the Juno D is a lower end keyboard it does have some decent quality sounds. However the rotary effects on the keyboard were sorely lacking. With the RT-20 problem is solved. It makes the Juno D sound like a more expensive higher end keyboard and will allow me to use the Juno D for a longer period of time and save up for the keyboard I want.
It is easy to use and the controls are simple and easy. With my expresion pedal pluged in to it I can control the rotary effect in real time wich is great. Without an expresion pedal you pretty much have to set it to one setting or reach down all the time to set it. So I would highly recomend using an expresion pedal with it.
The tone is great and it doesn't add any extra unwanted noise to my set up. You can control the bass and horn rotary seperatly wich is perfect. When I had a B-3 with a 122 cabinet I used to disconect the bass rotary so this is a big plus for me.
It looks cool. The visual rotary speed looks great on a dark stage too.
Perfect. It was easy to set up and use and had no problems so far.
