TS-9 Overdrive w/ more Med-Treble

[Zipporello]

hi all,

i've recently build a tonepad TS-9. It works very well.

Any suggest to increment (boost?) the mid-treble frequency (like keeley mod, maybe?)?

Really really thanks to all

Regards

The TS is already slanted pretty heavily toward the high mids/low treble area as it is.  Increasing the gain pot or the 51K in series with it will increase the passband gain and increase the relative level of those high mids compared to the rest of the signal.  Reducing the value of the 4k7 resistor to ground from the feedback path will have much the same result. 

Reducing the .047 cap there will move the whole frequency range up a bit, but not really "boost" anything.  Reducing the 51pf resistor might open up the top end a bit more at high gain settings.

Go to the AMZ site and look at the labnotes for the various tone-control mods one can do.  It explains the options very nicely.
