Removing the Bright Cap to
Tame Harsh Treble
If your amp has a treble response that
feels too harsh to your ears—especially
at lower volumes—you can tame it by
removing the bright cap. In a Marshall
amplifier such as a Super Lead, you simply remove the capacitor that lies across
two legs of the volume pot. This cap
allows the high frequencies in the guitar
signal to bypass being attenuated by the
taper of the volume pot, so removing this
cap eliminates the amp’s severe-sounding
highs at lower volumes.
To remove a bright cap, simply desolder the leads or clip them at a point
near the lugs on the pot. Be sure to leave
enough lead on the cap so that, if you
later decide to reinstall it, there will be
enough length left to be able to solder it
back into place.
To tame treble response in a Marshall head, simply clip or desolder the bright cap on the volume pot.
In case you decide to reverse the mod in the future, make sure you leave as much of the capacitor’s
leads intact (if you decide to clip it) to facilitate easy reinstallation.
