I really like the sound of the slower chorale Leslie effect. I started to try building one by butchering the grille of my Marshall 4x12 cab with a hacksaw..... I bought a small motor that runs at slow revs, a piezo speaker with an in-built 800Hz crossover, and two true-blue Leslie bakelite treble rotor horns (one as a backup).
But I've abandoned the idea because I got worried about the noise issues, how to mount the speaker and horn assembly (need a special bracket for it), and some feedback I read about other purposely made Leslie units (Motion Sound) that sounded too "snarky" and harsh when used with electric guitars.
I know that there is a Motion Sound guitar combo amp with a rotating speaker. And also, Mesa/Boogie made a rotating speaker cab called the Revolver- which is basically a 12" speaker (V30 or Black Shadow, not sure which) on a rotating post.
They could be good alternatives to the original rotating Leslie.
There's also the 'Doppola' I think, Dynacord, Cordovox too. A few there.
+1, I love those things. There is not much practicality in them, they are heavy, easily damaged, kinda problem ridden, and not useful for everything musically, but they sound fantastic for certain things
My local music store growing up had one of the Mesa Revolver things for a looooonnnnggggg time. I used to go in and play through it on a regular basis. Mind you, I was only in high school, but I remember the thing sounding really, really good. Only issue was it had washing machine syndrome really bad. Get it going fast, and it bounced around like nobody's business.
the speaker actually rotates, although with the Leslie, half of the cool tone came from the amp that went with it. I'm sure there are a number of ways you could duplicate the rotating spkr once you get past the signal coupling to the spkr The Leslie used a cool copper conductor path in a circle that was mounted on the bottom, and had arms that made the connection while rotating. Cool stuff
I used one of the big ass old school ones on my last record... thing sounded absolutely wicked cool, had a pedal that controlled the speed the speaker traveled at.
The mesa ones are cool I know someone that uses it in his live rig, I'd say look around for one of those!
Get a Digitech Expression Factory and run the outputs in stereo. It does that grindy thing awesome...Tesla Love Song, Badfinger No Matter, Zep...not a digi fan either, but this is one they got right
With some rotating speakers the speaker faces up and there is a bent horn over it the does the rotating.
Myself ..... I just use a Electric Mistress, Voodoo Vibe or Phase 90 most of the time as they are so much easier to haul around. But nothing really sounds like the real thing.
