Well, there's the "Tube Rotosphere" out there and it is no longer in production.
Reading about it led me to a funny experiement:
Let's take a tube overdrive (Hughes & Kettner "Tube Factor") and two chorus pedals and try to set up a Leslie emulation.
So, from left to right:
- Volume pedal to conrtol the attack of my guitar, the amount of drive from the Tube Factor and to do some volume swells.
- Tube Factor with channel 2 engaged for a bit of overdrive.
- The EHX stereo pulsar to split the signal and to give some tremolo effect.
- The "Super Chorus" with an EQ pedal for the low frequencies.
- The "Ultra Chorus" and a EQ pedal for the high frequencies.
- The "Time Core" stereo delay for a bit of room adding to the parallel chorus effects.
From there you could go to a stereo preamp or a two channel recording interface or even two separate amps. Even one guitar amp and one bass amp would be worth a try, I think.
For me it was an idea to try out, let me know about your results, if you ever tried something similar.
There's also a more practical application for the two chorus pedals I came across during this experiment:
The overdrive pedal, combined with the chorus pedals, this time in series.
Switching on the "Ultra Chorus" adds a sweet harmonic overtone to my guitar signal.
Adding the "Super Chorus" creates some additional space and ambient room for single notes.
Just keep the depth knob dialed down almost all the way to "mask" the chorus worble.
