Hi,
I heard the red snapper of a friend of mine. What a grat pedal!
It seems a Ts9 wthout the 'hoink' of a Ts9.
I didn't open it and I know the schematics is top secret, but I'd just like to know if it's a polished Screamer or if it's a more complex design, does anybody know it?
thank you,
bye
Take a TS style circuit and remove the input/output buffers, like on the Son of Screamer. Add asymetrical clipping. Increase the possible gain of the circuit (i.e. Drive control.) Add a variable low pass filter in the clipping loop, adjust other values to taste and you're done.
thanks!
what do you exactly mean with "a variable low pass filter "? Is there any example around?
thanks again!
In short, a low-pass filter allows lows to pass through (i.e. cuts high end). Similarly, a high pass filter allows highs to pass through (cuts lows). How do these apply in a TS circuit? Start with the Technology of the Tubescreamer article at GEO:

You may also want to study the schematics of the Boss SD-1, OD-1, FD2, etc. to get an idea of how the tone is shaped with various EQs. Then check out this article for more on tone shaping, cut off frequencies, and EQ in the TS circuit:

This can be used to calculate the value of a low pass filter:
