Welcome, you are looking at a great piece.
This is the Tech 21 NYC RotoChoir Electric Guitar Effects Pedal.
Imagine being able to get all the tone and nuance from a huge rotating speaker setup in something as small as a pedal?
Tech 21 did, and the RotoChoir is the result.
This pedal recreates both the rotating lower speaker and treble horn for a rich, accurate, modulation.
The controls are simple and laid out neatly for ease of use.
"Drive adds just the right amount of compression, harmonics and grit.
Low and High sculpt the tube amp emulation with powerful EQ curves.
The Fast/Slow footswitch allows users to ramp up, slow down or even stop the rotating speaker.
There's also a dedicated control to custom set the Top Speed of your rotor.
Want to vary the intensity of the effect?
Simply adjust the Position control to move the Roto Choir's virtual mic closer or further from the horns.
Other features include a biamped/single-speaker mode switch, stereo output and a Speaker Sim switch for direct recording."
This pedal is in very good overall condition as you can see in pictures- typical marks from normal use.
Tested and works as it should.
This is your chance to add a great pedal from Tech 21 to your rig. Don't pass this by!
