I'd like to boost 8kHz and up about 6 dB on the Fender Super-Sonic 22 burn channel.
Seems like C25 is the low pass filter that cuts signal above 1 kHz. So am I right that a 120 pF cap in parallel with R50 (220k) would achieve my objective, or am I in a world of hurt by doing that?
Is there a better place/way to meet my aims?
