    I don’t disagree with any of that. I was more so implying that the 4k7 more often referenced as the shunt resistor while the long tail resistor is the 10k in a Marshall. I will take a scratchy 5k with no shunt 10 times out of 10 for the even taper.

    This was the same way. It’s all about choosing the right bypass caps at each stages, Your basically allowing through more mods and high than you are bass. Then the Jose master adds a bunch of saturation and tames some high end
