I've had a Lovepedal Vibe and a Fulltone Deja 2 so I've compared those two pieces. I thought that the Deja was closer (almost dead on) to the original tones that I like by JH but my question is can this circuit be done without the photo cells and still sound authentic? I've listened to all the clips from virtually every maker and thought I had this settled but now I'm wondering if it's just that emulating it without the lights simply would be more expensive or impractical? Also, I'd be curious to hear anyone's Axe-Fx takes on Univibe especially if it nails either a Gilmore version, Hendrix or Trower. However, I'm really talking about an analog approach here.
