Mark IIC+ footswitch knob?

John posted this picture to Instagram and I’m wondering what is the additional knob added where the footswitch jack is on his 2 mark IIc+ amps?

I saw that and wondered the exact same thing

That’s known as the Petrucci mod - it’s a volume 1 mod that allows you to optimize the cleans to be “clean” while allowing all the grease and grind of the lead channel, without having to tweak either volume. It makes it a no-compromise two-channel amp.

If that was directed at my answer, it’s not a guess. It’s a fact.

It's nice to see Petrucci forgoing the silly beard dye. Gray pride!!!
