Ancient LPB-1 project

[Mark Hammer]

I was poking around in the basement the other day, and thought I'd pull out some old one-evening-projects compendiums from the good old days to browse through.  I used to buy these things for $3 on the newstands.

In one from 1979, titled as "99 Electronic Projects", I found a "Rocker's Mic Booster".  With the TV on in the background, I casually looked over it, taking in the general properties.  It was a single-transistor thing, with a handful of resistors of less common values, 430k, 43k, and....hey wait a second!  It was the schem for an LPB-1, to the dotted "i".

Funny how some of these things used to turn up in print.  Sometime around the same time period, or a few years later, I was poking around through one of those Rudolph Graf circuit encyclopedia books, in "music circuits", and copied the schems for the distortions (well, "fuzz boxes") that I found there.  Ten years later, when I knew better, turned out one was for the Fuzz Face.  You have to wonder where some of today's circuits will end up in 10 years' time.

That's interesting. Same thing goes for tube amp circuits to some degree...
