So I've been using these models primarily for a couple weeks and I have two questions...
Based on the release notes back in 17.00 "A “Presence Shift” switch has been added to certain “USA” amp models (those based on amps with a “Pull Shift” on the Presence knob). This switch is found under the Presence control and replicates the behavior when the Presence knob is pulled out on these amps. Note that the behavior of this switch is authentic and may result in volume reduction when active since the negative feedback is increased which lowers the loop gain"
Now isn't that already modeled or baked into the model?
Also does the presence without the shift engaged act like the triaxis cause from what I'm understanding from the manual its more of a high cut...? or am I wrong?
"PRESENCE:
This control usually regulates either brightness or negative feedback in the power section of an amplifier. In the TriAxis a whole new approach to this traditional circuit was taken. An actual dynamic feedback loop that
compresses the highs and upper treble frequencies makes this PRESENCE control the first of its’ kind. In applying for the patent for this unique (high compression) circuit, we discovered that this same basic concept can apply to many parts of the tube amp in guitar amplification and your TriAxis is the first benefactor of such a breakthrough. With greater understanding and patent grants behind us, lets talk sound.
As the PRESENCE control is increased, more highs are allowed to pass. The lower the signal strength at the input of this control, the more highs pass through it. The lower region of the
PRESENCE control dampens these high harmonics. The greater the signal strength at the circuit input becomes, the darker the sound becomes."
