I had a friend in the 60s and 70s who played and recorded with a very big name, but had his own combo on the side. When I went to see him at his gig, he had a trio w a female singer. Trio was nylon string guitar (miked only), drums, and upright bass through a small bass amp. (Ampeg flip top). This combo played a very crowded lounge that would seat 80 but usually was standing room only, so well over 100 patrons squeezed in at all times. They did the Pop music of the day: Jose Feliciano, Beatles, 5th Dimension, Motown hits, Oldies, filmscore tunes. All great players. Their "Sound Reinforcement" system? A Shure Vocalmaster tube PA with the tall columns. They played LOUD. So, as I got older, I really was impressed by the beautiful sound they got in that crowded cocktail lounge with just a tube head and two column speaker cabs. The handmade nylon string was mic'd by a Shure SM58 type mic, and it was really loud and clear. The vocals sounded like a record, just pristine. How did they do it? Skill. The band leader very carefully oriented the columns, and artfully adjusted the primitive PA system to get feedback-free volume for his guitar, and rich, well EQ'd tone for their vocals (two mikes). Good ears ... experience ... skill. I came to realize if they could fill the dance floor doing Pop Rock and Soul music with that instrumentation and that sound system, then I could learn to work practically any system I encountered thereafter. That's what inspired me to make gear work, no matter what.
