“I remember looking at that picture and thinking, ‘It’s going to be hard to be John Sebastian for a while.’”
Here is a really neat, short piece on John Sebastian. This guy is best know for having sung the theme song to the TV show “Welcome Back Kotter.” I’m not a gigantic fan, in fact his ultra-folkie image definitely clashes with my punk sensibilities. I’m fascinated by the guy simply because he appeared at both the Woodstock and the Isle of Wight festivals, in 1969 and 1970, respectively. So here is one guy who stood in front of two of the biggest music audiences ever assembled and lived to tell about it.

Alternate photo from Gibson Amp book
In writing the book Gibson Amplifiers, 1933-2008: 75 years of the Gold Tone I had the wonderful experience of seeing close-up a huge selection of really interesting amplifiers. This amp was really intriguing: a custom order GA-83 Stereo-Vib with two side speakers instead of four. The owner of this amplifier told me he bought it from the original owner who had himself ordered it from Gibson. The story goes that this man felt
four side speakers were too much, too complicated, so he ordered it with two. To my eye, it’s still a complex amplifier. The preamp section is up top, the power section on the bottom of the case. Controls include concentric knobs for volume and tone controls for each channel separately. That means you have ganged potentiometers, which are visible in this photo. There’s a good shot of a Stereo-Vib control panel in the book.
In stock configuration, the Stereo-Vib would send signal pulses to each speaker in succession, creating a whirling effect. I didn’t get to play this custom-order amp, but I would assume it utilized the same interesting concept. As the boutique amp market gets more and more saturated, it would be interesting to see how way-out designs like this one would fare.
