The first sytem through which I delivered a song was not a system but a Phillips tape recorder with the 1/4″ phone jack to take my Armaco crystal microphone (the one on the broomstick!). Later it was put through an Eaton Viking amplifier with my guitar.
Our first real PA was a Bogen tube head with six ” speakers on each side. The Bogen would only work when it wanted to and we basically had to scrap it.
Then came a wonder of technology: the Traynor YC3, 4 channel with reverb! Man, we could sound just like the guys on the radio with this outfit and it became a real joy to sing; so much so we put in singing more often with our instrumentals. This baby was tough as nails and the legend was that they tested the models by dropping them off buildings.
In the summer of ’72 I had strap-on pickup for my Gibson L-5 and this was plugged into the Traynor. There were three of us and we did Crosby, Stills \, Nash and Young, James Taylor, Jim Croce, America and a lot of acoustic stuff that were lounge favorites.
I had a lot of fun doing this but opted for a rock band. The Traynor was traded for the Kustom PA and we were in debt again.
