That's a Shin-ei. Did they check the tolerances of the LDRs while you had it repaired? That's what makes those units sound good, all the Photocells have to be in correct tolerances for a good vibe sound. I just had my Shin-ei Honey Vibe-Bro updated with better cells by the original maker of the unit, Dustin Sears and he owns one of Jimi Hendrix's Honey Uni-Vibes and he A/B'd it with mine and he said the waveform sounds very similar. I'd still like to own an original though. Your lucky to have one.
