I love the beer ads. Note the Ampex MM1000 in the Moog/Schaefer ad.
The Pioneer ad with Sonny Rollins is also interesting. That's the end of that early-mid-70's Pioneer
line. By 1979, the had phased in the all-brushed-stainless, rack-mount look for their top-line
components, plus the superb RT-707 and then RT-909 reel decks. No more belts driving anything except
the tape counter on those decks.
Note the vintage mics in the Satchmo and Urbie Green Schaefer commercials.
