"Very little weight - Huge rotary speaker experience"

As I said above, if weight, transportabilty, and my two previous back surgeries, were not a factor I would probably use my vintage 122. But, because all of these are very much factors, I appreciate all that Motion Sound has done in conceiving the extremely portable Pro 145.

Sound
I own a B-3 and two Leslie 122's. I just can't face moving the real Leslie's around at 140 lb. I own the new Nord C1 Combo Organ and am playing it thru the Pro 145. The organ sounds nearly identical thru the Pro 145 as it does thru my 122- which I am able to use thanks to Nord's 11 pin rotary speaker (and an 11 pin to 6 pin adapter). There is a difference, however, owing to the large wood cabinet that is the 122. But, the parameters that are tweakable on the Pro 145 allow the player to adjust for that to a nearly infinite degree.

Features
Motion Sound supplies a stomp box but you can use any kind of pedal to change the rotary speeds. I actually like using a digital piano pedal to do that. The polarity is reversed so that the speaker rotates on slow until you step on the pedal;when you step on it, it speeds up and slows down when you take your foot off. Most players use the slow speed more than the fast - at least I do - and a reversed polarity pedal acutally works better to achieve this end.

Ease of Use
The manual supplied with the unit goes over the features in detail but a few live gigs will bring it all into read more perspective. Especially important is the gain to volume ratio and the level at which you set your pre-amp mode. All of this gives you a virtually infinite number of possibilities for creating your "dream rotary speaker". Try doing that with a vintage 122!

Quality
It seems to be very sturdily made but the belts on the rotors could be confused with linguine. From what I've read, however, they're not breaking left and right so maybe they're just a new generation of indestructible plastic. I'm hoping!

Value
I think Pro 145 is fairly priced compared to every other alternative currently out there.

Manufacturer Support
I have dealt with Motion Sound personally. I called to ask them about using another pedal besides the stomp box that comes with the unit. Not only did I speak to a real-live technical person but he was extremely friendly, extremely helpful, and I came away with a really good feeling about the company which, for me, is huge.

The Wow Factor
The unit is "sexy" by virtue of it's compactness, bed-liner finish, power house ability in a small package, and nearly 360 degree, cloth -covered louvres that allow for true rotary speaker projection around the room.
