i don't think i'll get another rotary pedal. if this one dies (which it shows no signs of doing) i'd buy another one. obviously, it isn't a 122 or a 147, but for the size and price worth every penny.
Sound
i've owned this pedal for over a year now and it's never let me down. the sounds you can get are incredible. there's nothing quite like having a leslie at your feet. next to buying a 122 or a 147 it's the best sounding rotary emulator i've tried or heard. i owned a hammond XK-2 and the leslie sound didn't even start to compare.
Features
everything you need to define your sound is on this pedal, it's got all the knobs for rise time, balance and overdrive. there's even a switch to change the overdrive from guitar or keyboard. awesome. just like any boss pedal, it doesn't come with an adapter. but that's how boss is.
Ease of Use
plug and play. sounds great with everything at 12 o'clock. but if you're into customizing your sound, it's incredibly easy to do. everything is right at your fingertips. i keep mine on top of my keyboard and just adjust the sounds as i go. no programmable settings, just knobs.
Quality
just like most boss pedals it's built like a tank, like i said, i've had mine for just over a year and nothing has broken and it always sounds like the first time i played it.
Value
for what this pedal does, it's worth it. i mean..if you're an organist in jazz, rock, blues, etc you need a leslie or a simulator. this is the kind of pedal you'll have on all the time, every time you play. so when you think of it that way..250 isn't a lot to pay
The Wow Factor
for me, i wanted a leslie, but this thing gives you all the tones with out having to buy a truck to cart a cabinet around. that makes it pretty desirable don't you think?

Portability, sound quality, reliability, durability. Makes pretty much any keyboard sound like a Hammond. What's that worth to ya?
Sound
Very impressive, expressive, and tuned for recording and stage. I have not found a keyboard with a Leslie effect at any price that can match the realism this pedal emulates. I no longer lug my Motion Sound around to gigs. You are no longer restricted to miking a rotor to increase volume. Just use a larger amp! No quality loss.
Features
You can read about that elsewhere, but in real world use. Rotation speed, grunge, stereo! It's all there. Works well on organ and electric piano. If you forget your adapter (sold seperately) it runs on battery. Nice touch. Haven't changed batteries in 4 months. Heavy pedal so it won't slide away. Stomp worthy pedals.
Ease of Use
It takes a bit of fiddling but each knob returns definite audible changes so very soon you understand which knob does what. Only difficulty is having to reach down to your feet for adjustments. If only there were an extension with the controls that you could place on your keyboard.
Quality
Built like a tank. Don't drop it. You'll break the floor.
Value
Can't knock the product but it is pricey.
Manufacturer Support
Dunno.

Ummm. It stays below my shoe. The psych light's cool.

This is a keeper. It isn't going anywhere.
Sound
Very hard to find but I did. I haven't even begun to touch the surface of what the RT-20 will do. But there is no doubt. It's awesome!
Features
So much more than I expected.
Ease of Use
A bit of a learning curve for me but I don't have a whole lot of time to put into it.
Quality
Very nice.
Value
You're getting what you pay for.
Manufacturer Support
Rolandus.co was helpful with a couple of questions.
The Wow Factor
It is fun to use in a dark room but that's not really all that important.

Sound
Clear and very realistic lesly sound.
Features
Once you get the foot pedal, the sky`s the limit
Ease of Use
Simple as they come
Quality
Solid as a rock
Value
I think that all musical equipment is much too expensive.
Manufacturer Support
I would imagine that it would be great but I`ve never needed it.
The Wow Factor
I can`t get over how closely this pedal resembles an actual Lesly. If it`s a Lesly sound that you want, this is exactly what you need and in my experience,20 years, it`s the best product of it`s type on the market.
