COLORSOUND: Treble Booster, Steve Williams (partial trace)

So there are a few bits missing, but if you are familiar with treble boosters, I'm sure you'll work it out.  Being a small and simple circuit, it's a good candidate for breadboarding.

The filter pot is your standard input blend, probably similar to the values that Steve Williams uses in his Pigdog Competition Special boosters, which is followed by a silicon treble booster with a coupling cap and volume pot attached to the end.  So a little different to a Range Master in that sense.

Updated layout:  Thanks Zollinger Analog for pointing out that there is actually a link between pins 1 & 2.   I couldn't see what was right in front of me...  the link is sitting on the other side of the pot.

COLORSOUND TREBLE BOOSTER - STEVE WILLIAMS

Important to note that this is a partial trace - you may have to test this and work a few things out yourself.

With a 5n / 100n cap and a 100k filter pot, the response on the base of the transistor looks like this.  The output looks about the same with the 100n and 100k pot.  A 47n cap looks pretty similar as well.

Being a silicon boost, they tend to be a cleaner wave than a germanium boost, although this does look to get some dirt as more bass is introduced.  It is just a simulation, so real-life results may differ - and honestly, you never want to hear a silicon treble boost that is not overdriving an amp - horrid...
