I just uploaded my latest emulation of the rotovibe FX, I 'm often close to buying a déjà vibe or a similar external good univibe clone, but listening to samples and reviews everywhere led me to some new trials.
My 1st trails where good but there was a missing asymmetrical component, a kind of warble . I fooled the ring mod with a trem stomp in front and that added a lot.
it might be worth trying the same hack with a vibrato, phaser vib, rotary ...
let me know your thoughts, I don't got any ref. pedal ATM.
