Hey guys

Theoretically here, what would the following tweak do to the tone?

Change cathode cap/resistor combo (the cap and resistor running to pin 3) of V1 and V2 from:

820k/25uf to 1.5k/4.7uf on V1

and

1.5k/25uf to 1.5k/47uf on V2

Typically, lowering the resistor will increase the gain and increasing the cap will permit more frequencies to pass. Increasing the cap value could be like incresing the distortion for a wider sound spectrum. 25uF would be pretty broad and 0.68 uF quite focused.

For example, the boost switch in the sIII drops the resistance and adds a cap when engaged.
