You are one schizophrenic, pseudo-scientific, lying, criminal PITA

preamp circuits in old clean tone amps by placing a 25uf/25v cap
across the cathode resistor of a preamp tube. In a 12AX7, the cathodes
are pins 3 and 8.SUCKMYWARTyCHEESEDICK!
If you look at the socket, those pins will go to a cathode resistor
whose value could range from 470 ohms to 4.7K.
YOU****SNIFFINGBABYHUMPER!!
If that ASININE YANK SCUMBAG! resistor does not have a bypass cap across
it, it's considered "unbypassed", and the tube will not supply full
gain. The HAIRY NIPPLED **** FACE! size of the cap will effect the
frequency response of the gain. A smaller cap will have more highs.
TEABAGGED INFANT FELCHING BALLSUCK!!! The most common caps measure 25uf
@ 25v. If an amp is too boomy-sounding (too much bass), try bypassing
the cathode resistor on the preamp tube with a 10uf, 5uf or even a 1uf.
IMPACTED PIG PENIS SUCKMONKEY!The smaller the value, the more it will
tame low-end response and accentuate high end. If there are multiple
gain stages, check to se whether the others are bypassed.
GREASE FARTING SKIDMARK LICKER!!! You could improve gain by 10db or more
merely COCKCHEESE GARGLER! by adding a couple of bypass caps! When
adding the cap, remember -its negative side always goes to ground, so
the positive TWISTED SMELLY SACK SUCKING CLAUDEL! always goes to the
tube's cathode. Electronically, this will put the cap directly across
the resistor.

One important caveat to the forgoing...ITCHY DICKPLUG SUCKWEASLE! The
phase inverter DUMB**** MUSO! tube shouldn't be included when adding bypass ******** GROPER FIST ****ASS!! caps to the circuit. As you know, this baby delivers signal to the output tubes and is PITA SEPTIC **** DISCHARGE!! usually closest to PILES OF ASININE CRAPOLOGY!! them. It's part of the design to have unbypassed cathode resistors here, so stay away from HOPE YOUR TINY BALLS ROT OFF!! adding one here YOU ANENCEPHALIC VERMIN CRACK!!
