Also, maybe I should describe the intesity of the jump a little clearer since there seems to be some confusion there as well.
Initially, I stated it was akin to turning the LEVEL (volume) knob on a typical dirt pedal (not gain or distortion knob) up 20%. So that means from half (or noon) to 70% (or 2:00).
I would also be confident in using the same metric as applied to a clean 15w solid state amp.
Another accurate way to describe it would be to say that if you were watching your television at a certain volume, and the volume increased as much as THE JUMP, it would most certainly illicit a “WTF!?” response.
Yet another way to put it: the jump is almost twice as loud as I would ever want a lead boost, in comparison with the base volume.
I don’t know what to measure, or if I have the proper equipment to measure such low voltage signal level. This is the best I can do to clarify.
As I said before, it’s a significant jump.
