Default Re: Transistors wanted

I've got a few old books from the 60's/70's which feature FUZZ boxes and other effects. From what I read it's only a matter of driving the circuit into overload ,and generating square waves. Perhaps, OP might look at doing this with IC's , looking back at how the likes of GEC and the olde telecomms makers produced ye olde carrier generation frequencies to modulate audio into hypergroup ranges. Take one frequency ( as in take two hares) , amplify it and pass it across a coil. When the coil saturates- it generates harmonics. The harmonics were simply rectified ( to remove odd harmonics) and filtered ( to get the desired frequency) .
When the wave is changed from sine to square, there's all the harmonics wanted.
