Rotary Speakers - the Easy Way

Wouldn't it be great if you could conjure up the celestial sounds of a vintage rotary speaker cabinet by simply plugging your guitar into a pedal and going direct? Well, now you can - with the Tech 21 Roto Choir Rotary Speaker Emulation Pedal.

Roto Choir re-creates both the rotary lower speaker and the treble rotor horn to achieve that complex, multi-dimensional tone you know and love. What's more, Roto Choir delivers the entire signal chain, from the original tube power amp to the speaker and high-frequency rotor horn, as well as the microphone used to capture it. How does it pull that off? Well, Tech 21 has been at this awhile; there's some slick technology under the hood.

Roto Choir's simple controls offer you a wealth of sonic options. The Fast/Slow footswitch allows you to ramp up, slow down, or even stop the rotary speaker. Drive adds just the right amount of compression, harmonics and grit. Low and High sculpt the tube amp emulation with powerful EQ. You can also control the top speed of your rotor. To vary the intensity of the effect, you simply adjust the Position control to move the Roto Choir's virtual mic relative to the horns. Other features include a bi-amped/single-speaker mode switch, stereo output and a speaker-simulation switch for direct recording. So, if it's classic rotary-speaker sounds you're after, plug into Roto Choir and see how easy it is to get those lush, swirling tones.

Great pedal for chorus-hating pedal buffs

I wanted a Leslie sound but have never really been a fan of Chorus-type pedals.And who doesn't like the Badge sound? I saw some demos of this online and liked the sounds so picked one up. Anyhoo I love this pedal as it has a lot of sounds from old school Leslie to some cool original sounds you can get especially with other pedals. Best of all it doesn't sound "chorus-y" and it's a lot of fun. Plenty of things to play with but not really complicated and quick to get a nice tone.

Tech 21 Roto Choir

I finally have a "Leslie" Pedal thats worth every stickin' penny I have tried and or owned nearly every "Leslie" simulator ever put out over the last 25+ years. Uni-vibes and roto-vibes were ok/best of the lot and the Uni-Vibe will stay on my pedal board because it has a nice niche' to fill but... The Tech 21 Roto-Choir is just off the grid. The over all quality of the sound is excellent, its easy to use, and like a real Leslie, it has a sound that is ever so slightly crack-ly and both trebly yet has that terrific midrange. What does this have that seemingly all the other simulators dont have/do? It has a mic placement dial, which IMO was freaking brilliant. It allows you to adjust the sound so that if you had a mic up close on the cabinet it would give that (sorry, this is the best discriptor I can make an analogy to) full whoosh whoosh whoosh of a spinning speaker, of move it back so that its a little more blended wide whoosh, or move the "mic" further back to get that wide WHOOOOOOOSH that is just stupidly rich and full... It also responds quite nicely to being cranked up or softly. I played it through a tiny Crate, a Fender Twin Reverb, and a vintage Vox AC30 and was pleased with it on all three at all volumn levels. FWIW Guitar Player Magazine gave it an editors choice some time last year for best in its catagory. Want that Leslie sound but dont want a monster heavy cab to tote around... the Tech 21 IS the answer! Also, for people asking about a stereo version. Leslie's are not stereo and not many guitar players have the roadie help or can afford two leslies. A single, MONO is all thats really needed, ever.

Its like a leslie in a cigar box

Sounds as good if not better than playing through an actual leslie cabinet.
