Feature:
I love everything about it except Motionsound failed to put an XLR DI output on the speaker output. It does however have stereo output xlr on internal microphones on the rotating horn. Why they didn't think of the bottom end, or the stereo channels needing a balanced Direct output I can't imagine. For this short coming, I give it an 8 rather than a perfect 10.

Quality:
I get constant completments on the sound of this amplifier. I can even feed a cheap organ through the Leslie simulating channel and it sounds like something from a 60's rock album. Other keyboard players and musicians all bragg on this amp. I wouldn't consider any other keyboard amp. This amplifier is a life time investment for me. This amplifier is the understated, unknown best out there.

Value:
Expensive period, but I wouldn't take any other amp so I guess it's worth it.

Desirability:
It is a nice sized amp. I set the amp on top of the flight case when I play. It puts it a the perfect height behind me. I turn it lound enough to monitor myself and let the sound man take it from there. The soundman is always bragging on the "source" of sound I'm sending him.

Sound:
This is hands down the very best keyboard amplifier out there today. The Leslie sound is the closest thing to a real Leslie I've heard. The stereo channels match or excede any other keyboard amp out there, plus it is a stereo amplifier.

Ease of Use:
Any dummy can operate this amp and get a great sound.

Support:
I've had to call them as I had some transit damage, the Motionsound folks were quick to respond with support.

Overall:
This amplifier is the cat's meow for the keyboard player who wants a great keyboard amp AND a Leslie sound that is very close to a real Leslie.

Feature:
Very solidly built. Tube overdrive sounds good. Wish list: LED indicator on pedal for leslie speed; castors should be mounted at factory, if requested, not left for you to do.

Quality:
Fit and finish is excellent. I plan to gig with it...will report back.

Value:
Slightly pricy - but worth it for the "pro" sound and the leslie effect.

Desirability:
Looks great. Sounds great. What more do you want?

Sound:
Beautiful sounding. The rotating speaker "leslie" effect is heavenly with either my voce v5 or kurzweil Kb3 mode. The stereo expander effect works great with strings and piano - exactly as claimed.

Support:
Have only dealt with the company by e-mail, as there were no local distributors. They were helpful.

Feature:
Casters should be standard equipment as this amp is heavier than a dead priest. The LEDs for rotary speed should also be standard although Motion Sound does have a schematic on their website.

Quality:
Handles are a bit hard to grip, but well positioned

Value:
a bit expensive

Desirability:
I wanted it so bad I bought it

Sound:
Great mellow Leslie sound, loud no distortion, excellent

Support:
no dealings with the manf. owners manual looks like a rough draft on copy paper, but informative. Would like to have more suggestions on how to hook up to the two amps with one keyboard.

Overall:
Love it

Feature:
Has everything I could want with the exception of a real snarl overdrive distortion, but I get that from the combo-pedal I'm using.

Quality:
I was a little disappointed that I blew the horn in the first 6 months of ownership. It ran me about $117 dollars to fix it with a more sturdy one. The horn the unit ships with now is the more sturdy one (the next rev. 1.2), so most people won't experiance the same problem. It has worked wonderfully ever since it was repaired.

Value:
If you bought the first revision (with the 1.1 horn) I would say the unit is not reliable enough. However, the second version w/the better horn would be worth the money.

Desirability:
People who see it when I play out w/my band ask me about it all the time. They want to know what it is/who makes it/where to get one. Its quite a smart looking amp.

Sound:
This amp sounds almost perfect (Getting a little horn buzz, but can't be heard at performance level). It takes a little getting used to the fast/slow and stop foot pedal buttons (used to a gas pedal design), but all-in-all quite a robust design. Makes my cheap-o Yamaha keyboard sound like a real organ.

Support:
I emailed the company to see if they still made a "gas-pedal" type speed pedal for it, and they got back to me in a week -- not bad. Unfortunately they don't make the "gas-pedal" anymore. Oh, well.

Overall:
After I repaired it, I would never want to get rid of it...Its THAT GOOD SOUNDING. It can play quite loudly.

This thing had to be designed by a keyboard player. It's got the rotor, enough inputs, and the power to carry it all off. Finally, one amp that covers all my boards without breaking my back. The big organ sound with my XB-2 is the closest your going to get folks. It's the set up that I can be seen and heard with and not feel or sound like a sell out, and I'm an old hippie fart who's used to playing only the real thing.

My rig is a Roland RD-600 and Hammond XK-2. The piano sounds great -very musical. Need to roll off some bass at club volume levels but it still sounds really good. Great tone control.

The stereo expander is quite unbelievable. It will break up at high volumes so I can't use this at club gigs. Really nice effect however.

The rotary channel is serious and gets loud. I can overdrive the tube by cranking the pre and then using the volume control on the XK-2 -this sounds best. If I ever get in trouble and need more 'stortion I can crank the overdrive on the XK-2. I disagree with the Italian guy about the XK-2 -the XK-2 through the motion sound is far better for deep purple than the roland. I have never owned a real Hammond or Leslie but have heard them live and it is magic. The XK-2 and Motion sound do not deliver the same exact sonic experience that I have heard BUT rather they deliver a very closely related listening experience. Pretty FG.

Looking at a new Novation KS-4 to fill the third channel. Distorted filter resonance should test the motion sound pretty well.

Gets pretty loud but I could really use two of these puppies! That would crank.

Also, a monitor input from the board (not assigned to the output section) would be nice.

Good unit. Akward to carry. Needs an LED on the footswitch.

There is nothing better. I've tried a million amps for my setup (Rhodes and Hammond), but I could never find the perfect fit. This amp has it---power, warmth, versatility...it even keeps the weight down.

If you want a real, tube-driven rotating speaker, and you need clean channels along with it, there's no better way to go.

I gig it with my Yamaha keyboards- closest thing
yet to the real thing without the hassle and
with a variable sound capability with low
weight and compact portability...

I have used mine for 3 years now. It has held up well with no problems. The sound quality is more biased toward organ side. The keyboard side adds some lower mid-range coloration to the sound. Otherwise, it's still best in class and sounds better than most other keyboard speakers out there.

Feature:
Fast, slow & stop pedal, wow, lack of a light on pedal for fast/ slow/stop always has me checking to see what rotor is doing, light on amp hard to see from anywhere.

Quality:
I got an early model, black finish on cabinet was garbage, ended up rhinolining it myself. Pots for mic controls on rotor fell in, not a quality piece of work. Ended up buying a amp case for it, which I highly recommend anyone that buys this does.

Value:
Overpriced because it has a rotor, like a leslie, better watch it guys, those stereo sims are sounding pretty good, and I love the weight ratio aspect.

Desirability:
Always get comments from sound men who want to know what the hell it is

Sound:
OK Leslie sound, piano & synth channel seems to get lost, not great bottom end, I use a pro 3 to supplement the rotor and a monitor amp for piano. This is not a leslie, but it could sound a lot closer with a little more effort by Motion Sound. Subwoofer output, mixed XLR line out jacks, better mikes and control of same for horn, those cheap pots are a waste of time. For the price paid, should be more top of the line.

Ease of Use:
Good tube overdrive, but again, low light situations make it very hard to decipher panel settings, not pleased with chorus sound

Support:
Called Motion sound about problems with cabinet wear and pots, said pretty much "too effin bad, pal"

Overall:
I'm going to use it for a while, not a recording piece of gear definitely, small venue OK.
