I remember this program being shown on our local PBS station back around that time period. I recorded the episodes because I thought they were done quite well. It may seem dated and elementary today but at the time it was informative and entertaining. I probably still have them on VHS but I seem to recall missing one episode because the PBS station decided to show that one episode at a different time. And unfortunately they never replayed it.
I also recall one episode where they discussed amplification for reggae bass players, where you either use two amps or two channels, with one channel providing the note definition (i.e., using treble/mid) and the second signal flow being mostly the low-end sound range. Kind of like a sub-woofer. I always thought that would be worth experimenting with if I were a bass player.
