I thought I was crazy for years hearing occasional high-pitched ringing tones, until I realized I'd rented a room next to Robert Fripp. Yes, this was a joke. I was a part of a very loud rock band during most of the 1980s and early 1990s. The last couple years I used earplugs all the time and it really helped, but some of those early years probably did untold damage yet unrealized (we considered it a point of pride back in '84 that we pegged a friends' Radio Shack db meter. Oh boy.) Anyway, since '92 I've been doing mostly solo stuff at conversation level - my Boogie Studio preamp lets me get a SCREAMIN' tone if needed yet at conversational levels. I don't miss the blast of wind from my combo amp, either, but is used sparingly. -Todd.
