How to add presence pot same as version 2

Strymon ---> Previous Brand "Damage Control" under Peavey -----> Service, Spare Part

When turn down pot the tone also changed. Anyone can advise how to mod it. Thank you If you mean you lose treble when you turn down the level pot, then you could probably add a so-called 'treble bleed' cap and resistor in parallel across pins 2 and 3 of the pot, like what is done for guitar wiring....
