The mini-DV's photocells were knocked-off from 4 of my Best Vintage Univibe's Cells. This makes all the difference in the world because it's not just about correct resistance. The original 1960's Vibe's (and our) photocells have tall sides and a glass top which react differently according to how much light actually gets let in. The photocell properties/physical layout, correct bulb, and correct mirrored shroud all are key components to getting the right Throb, thickness, tone. I don't care if you loved or hated past Fulltone vibes, plug the mini Deja' in next to ANY clone or original, I dare you.
