Yup, and of course he used MXR going way back to the Gene Simmons demo album, which I think is what finally got them their first contract and IMHO is good-enough to consider an actual VH album.
Considering it was a demo and mixed in the late '70s I reckon the engineering and mixing were top-notch except for a couple o' spots where the guitar suddenly got a whole-lot louder (too-loud).
