thanks for the info on the encore frequency shifter john..
it's about $1500 cheaper than the cotk module!

My only experience with any of the above is that I've got an Encore frequency shifter. I like it a lot! I've actually not tried to do an "elf voice" effect with it, but it can definitely be used on voice. However...

Analog frequency shifting and digital pitch shifting are very different. Frequency shifting causes harmonics to become inharmonic (reminiscent of ring modulation, in a way) whereas pitch shifting shifts all frequencies by the same harmonic interval.

BTW, the Digitech Whammy pedal is pretty cool for cheap pitch shifting fun.

Frequency shifting *adds* a fixed offset to harmonics. So it is  
indeed very much like ring modulation - in fact it's ring modulation  
with the difference products suppressed.

Pitch shifting *multiplies* harmonics by a fixed amount. So the  
relative offsets stay the same.

If you want an elf/chipmunk voice, a pitch shifter will probably do a  
better job. Frequency shifters are better for scary distorted monster  
voices.

If you can find someone with the Arturia Virtual Moog VST plug-in, it  
has a frequency shifter module which sounds not unlike a hardware box.

(Actually you can buy a Virtual Moog and a PC to run it on for the  
cost of a hardware frequency shifter. If it were me, I'd probably  
spend the money on other modules. ;) )

there are also alot of digital effects processors which have  
frequency shifting.

at the high end are the eventide h8k and the TC Firworx, at the low  
end are some Zoom boxes and one of the Alesis ModFX boxen.
