There is no DSP or algorithm difference between the Whammy V and Ricochet, there shouldn't be any difference sonically between the two. The Bass Whammy has the same algorithm but we tweaked the detector to better process the longer waveforms of low frequencies.
I think a Bass Ricochet would garner more than a few fans, too. I owned the Ricochet for a short while and what it did was perfect for me. The tracking wasn't too hot on bass, however, which is a real shame as I loved everything else about the pedal.
