I posted this over at the RPF.
Basically I just finished up a new low-cost trooper and Fett voice changer/amp. It does both effects and has several new features for a voice changer in its price class. It is still not as accurate as Vortex, but is meant to be more of a "bang for the buck" unit.
I just put a few fett samples up, please let me know what you think.
Feel free to contact me if anyone is interested. Thanks for looking.
