I got that from Howard himself, when I interviewed him about a year ago, and he lists it on his website as one of the designs he created – but many people may have worked on it at the time. I’ll have to contact Michael for some info, and Howard again, as I will be adding the Deluxe BM to my website soon. Still doing the research.

When you interviewed Howard in ’99, ‘Stones, Clones, & “Muffs” was the article title, but there was no mention of a Big Muff in the interview I read. Was there more to it that did not get printed?

Definitely the preferable version.

Here is another. This ad is from 1974 and shows the reactor tower shaped knobs used on a bunch of EHX pedals (and some of the OEM EHX pedals from around 1973-74). Note that there is no word OFF in the Big Muff and Black Finger graphics – another way of dating those pedals.

I think DiscoFreq posted an ad with that same Bad Stone somewhere here before. The mummy graphic came before the black and orange, so I would assume the pcb is similar to the Mummy version. I like that the ad copy says 1080 degrees instead of 180 like the other ads. I guess this version makes you dizzy when you hear it!
