More Treble Response Mod
"In general, simple, single-channel, full-bandwidth compressors of this type have the effect of creating the illusion of treble being attenuated (just as they create the *illusion* that the instument sustains better/longer). There would seem to be two or three paths towards improving that. One is to compress less. Another is to mix in a bit of uncompressed treble with the compressed signal. Another is to reshape the frequency response of the fully compressed signal.
Although there are probably better ways to do it, I sent in an Orange Squeezer mod to JD Sleep for posting on generalguitargadgets that attempts to accomplish option 3. It uses a simple bypass cap on the volume control that lets more treble through, relative to bass, as you turn the volume down. If you look at the Dyna/Ross schem (and bunch of other oddly enough), you'll see that the output path consists of a 0.05µF cap. a 10K fixed resistor, and a 50K pot. That 10K resistor is a mystery to me as to why its there, but lets just count our blessings and not ask too many questions.
How is the 10K resistor a blessing? Because it allows you to stick in a bypass cap. Note that the 10K+50K arrangement behaves as if it is a 60K pot that can never be turned up ALL the way. If a bypass cap could work on a 50K pot, why couldn't it work on a 60K pot? The nice thing here is that the treble boost it provides is applied across the entire range of volume-pot settings. Try a 1500pF (0.0015µF) cap in parallel with the 10K resistor for starters. If my assumptions and math are right, that should give a slight advantage to content above 2200hz in your output signal. That may or may not be enough to do the trick for you."
, yes it was surelly a typo error from the build reporter...
