Yes, he is bad to the bone, so he drinks alone one bourbon, one scotch one beer.
Metaphorically speaking as above, I mean he is bad to the audio myths, he keeps on promoting the make alone (DIY), straight, sensible, effective speakers.
Thorogood openly admits he is no genius, no innovator, but he has common sense and some guitar chops. Just genius into being very clever. He still gigs.
Zaph never claimed innovation, never promoted top of the rank kit, or extravaganza. Just common sense. And look, his ideas are making everyday DIY people happy.
For open loudspeaker philosophy, live presence, and higher musical correctness goals, look towards Lynn. He is the main man for pushing the DIY thinkers IMHO. No concrete guides there, mind you.
Say, if the Zaph - Thorogood analogy stands, then think of Lynn as Charlie Parker.
