When I was a junior in high school and was a drummer in bands that actually made money!
I remember going off to college with my Kenwood integrated amp, a Dual 1219 turntable with a Shure V15 Type 2 cartridge, a Wollensak reel-to-reel, the Koss Pro 4B headphones and a pair of Dynaco bookshelf speakers.
As an adult, when I could see "the light at the end of the tunnel" with my youngest's college expenses, that's the time "the bug" cost the most (in terms of dollars!)
