Good sound

I have had 4 leslies in my 45yre of playing and the pro 3x sounds just as good. Use a good low simulater amp and you will be satisfide

Move air, not bits

First, I should say I've never played thru any kind of Leslie or "spinning speaker thingie" before. Up to now, it's been all sims. So I can't say this is just like a real Leslie, better than this model or not as good as that one. But for those of you wondering, it *is* better to move air than to move bits. I played it with my band for the first time last Saturday, and they really dug it, including the guy we were trying out on guitar (who we've asked to join us based on his performance that day). It was really cool, and even the recordings picked up the effect bouncing around the room (I record every jam with a stereo pair so we can listen back to what we did as well as find undiscovered gems instead of losing them to the ether).

The Pro-3X was enough to fill our small "studio" room against the drummer, bass, and guitar player. The way my amp is set up, the Pro-3X is about at ear level when I'm sitting down. My right ear gets the brunt of it, which I do have to be careful about. It can be piercing!

Providing the organ tone was my Roland VK-7. What was nice was that when you Bypass the rotary sim built-in the VK-7, you also bypass the amp model in the VK-7 as well (this only works if the amp model is Type I or Type II). This allows you to use the V-FET circuit in the Pro-3X to provide the overdrive. Combined with an expression pedal plugged into the VK-7, I was able to nicely control volume that went into overdrive as I pushed into the full range of the pedal and get some nice biting organ tones when I needed them.

So far, so good. I am very happy with it.

I should mention that I did have a weird glitch setting it up and moving it around shortly after it arrived. I had set it up in one location, and decided to move it to another. When I did that, I plugged the cable for the low end into Mix instead of Sim accidentally. For those that don't know, Sim gives just the low end rotor sim, while Mix gives you a controllable mix of low end and the miced real upper rotor. This can be used to send the complete signal to a PA or house mix, for example. So I moved the plug from Mix to Sim, and got nothing out of it, no static, not intermittent, nothing except hum. I played around with it, switching the plug back and forth between the two jacks, trying another cable (the cable I was using was brand new), running the output through my mixer instead of directly to one of my amp channels, etc. Suddenly, plugging back into Sim, it worked. A bit more playing with it and it came and went, but then it worked and has continued to work since. At this point, I'm happy to say it is working, and speaking with the guys at Motion Sound, they did not know what the issue was, as there is no switch or contact like that in the jack nor any setting that would disable the Sim output. I will call them while it is happening if it happens again.

In summary, if you are using a sim built into your clone, or are considering moving air for any reason, you owe it to yourself to check this or something like it out. Just remember that some boards may have the Leslie effect in the samples themselves, and in that case, you'd be running the Leslie effect through the rotary speaker, which you probably don't want to do. But, if you can bypass the rotary effect, then you will find there is nothing like using a real rotary.

Pro-3x Sound Enhancement

I wrote 2 reviews already on this great rotary speaker, but I just found another way to maximize the overall quality of the sound on the recommendation of a techie friend of mine. Run cords from the left and right outputs of your keys/organ, DIRECTLY to your main AMP, instead of your left output running to the Pro-3x as the owners manual suggests. What this does is send the full maximized left & right channel signals to your MAIN amp. Then run a cord from your keys/organ HEADPHONE output, DIRECTLY to your Pro-3x, then a chord from the Sim output of the Pro-3x to a separate channel on the MAIN amp. Now you have 3 sources of sound from your keys/organ going to your main amp. That increases the quality and volume of the sound coming from both amps at least 30%-50%! Enjoy!!!

Excellent Leslie Simulator !!!!!

The Motion Sound Pro3X is a great addition to your Organ sound. I have only had mine for a week and still trying to get the settings right for the sounds I want, but it has blown me away. I used to have 2 Leslie 122s with a B-3 and this is the closest simulator I have seen since.I am using a E-MU B3 sound module. I believe a good quality low rotor sim amp is the key for getting that clear beautiful low end sound along with the crisp highs from the Horn.You would not be sorry for purchasing one of these Pro3X horns. Have a Great Day and ROCK ON !!!!!

Leslie in a box.....SWEEEEEET!

From the second that I turned this unit on it kicked out nothing but rotary sweetness! After about an hour of playing my xk-2 through this unit I was completely blown away....the fullness of the sound will certainly fool the most extreme B3 player...The lows are full and bold and the highs sparkle like the rotor on a 147....I did an experiment with a mic on the rotor as well as using the mix out...an AWESOME stereo-type effect....and if you get the mic in the right position, you get that wonderful mechanical sound. Five stars from this player. BRAVO Motion-Sound....PERFECTION!!

Great unit....even records well in a live environment!

I love motion sound products, and have the tube version of the Pro-3X. I have played this version, too, and really like it. Great tone, and very good control over the overall sound. The tubes in the Pro-3t are hard to replace (you need to disassemble the unit to get to the tube), so this version is more convenient.

If you really want a great tone, run your organ/clone through a speakeasy vintage tube preamp before running the input to the motion sound. Oh - and you can ignore all of the posts here that talk about running your keyboard outputs direct into your amp and the headphone output to the motion sound. If your main amp is a good one, you won't want to blend a crappy direct sound with the motion sound - at least not for organ sounds. The only way that makes sense is to run an A/B switch box and blend a direct/stereo sound with the motion sound .... for RHODES patches.

If you leave the motion sound speed on slow, and blend with the direct/stereo Rhodes sound, you end up with a killer overall Rhodes tone. You don't need to do this with a real Rhodes, though...

Nice sound, beats lugging a 122

I've used lots of Leslie effects and for a while toted a 710 Leslie around. For many years I osed the in-board effect on my Roland VK-7, but when I got my Nord C-1, I wasn't happy with the built-in, so I got a 3X. GREAT sound, love the ability to send the mixed signal to the board. The wind up and wind down are terrific, the real Doppler of the horn makes a terrific difference. Would I have a 122 if I had a roadie? No, I'd have 2 of them. But for the small rooms I'm playing now and my advanced age, this is a GREAT box. Highly recommended, really rocks.

Pro-3X location

One important thing I forget to share in my review, is that you get a fuller, better sound and stereo effect, if you separate the Pro-3X from your amp by at least 5 ft. You can hear the frequencies below 800 HZ through your amp speakers as well as through the Pro-3X speakers. I'm not sure how it's done electronically, but when the Pro-3x is hooked-up to your amp, you can get the full organ sound out of both units simultaneously.

The Pro-3X - A Welcome Addition

I recently purchased a Pro-3X from Jeff and Shane - just on their recommendation without ever hearing it before. I did not know what to expect - I already had heard the Pro-145 and liked that amp very much. But I already had the Roland KC-500 and just wanted to add a real spinning rotor to authenticate the Leslie sound for use with my Hammond XM-2 module (also purchased from Jeff and Shane). The amp sound is very close to that of the Leslie 145 and 122. With the proper tweaking, you can get it to sound exactly like those Leslies. The Pro-3X only has one input for a 1/4" line running from your keyboard output channel. Then you run a line from the Pro-3x SIM output to your amplifier channel. Since most keyboards have a pair of output channels, I found that also running a line from the second keyboard channel directly to a separate channel on my amplifier (my KC-500), gives me a fatter organ sound when mixed with the channel the Pro-3X is connected to. Since my XM-2 already has a fabulous digital leslie simulation onboard, you then have the option of kicking in this leslie in addition to the Pro-3Xs leslie sound. You can have interesting effects by turning on the slow speed rotor on the Pro-3X, and then adding the fast rotor on you keyboard to the sound. There are lots of possible combinations - the sky is the limit! The price and the low weight of this unit, makes it superior to having to lug a real Leslie around to your next gig. I'm very pleased with this amp.
