Mic Kaczmarczik has been collection USENET articles about guitars, equipment, pickup, techniques, players, and so on for some time. Mic has graciously granted permission to post the stuff on the JT30 page on the off chance that it might be useful in the context of Blues Harmonica. Mic is not responsible for the content, just the collection.

Fender Amps ,Tubes
Just Added DIY (do it yourself), Caps,
