That's a nice story. Thanks for bringing it to our attention. I'm sure they're happy to be working together again.
Funny thing, though. I was well aware of David DiFrancesco, since he had a number of articles in Polyphony magazine, forty years back. But I had absolutely no idea that his middle initial was "O". Presumably, given he was the founder, D-O-D stands for David O. DiFrancesco., same way JHS stands for Josh H. Scott. But to stem any rumours, MXR is not someone's initials. Apparently, those guys were making mixers, initially, before branching into pedals, and MXR was simply a coy way of misspelling "mixer". And, as I hope we all know, EHX is also NOT someone's initials, but merely an abbreviation of Electro-Harmonix.
