rdfs:comment """
The TooB Power Stage provides flexible and nuanced emulations of guitar amp power stages.
The goal of TooB Power Stage is emulate the best features of real tube amps without slavishly
reproducing the undesirable features as well.
TooB Power Stage provides 3 consecutive gain stages, each of which can be overdriven to varying
degrees. Power transformer sag is emulated using the SAG and SAGD controls, which emulate the
volume and distortion effects introduced when power transformer voltage sags.
Each gain section expects an input level that is nominally in the range of 12db to 0db.
It's ok if the levels are slightly over 0db, but they should not be massively over. Use the
Trim control to adjust input signal levels.
The Gain controls use oversampled atan wave shaping to emulate the effect of overdriving
gain stages. Atan wave shaping provides rich even-order harmonics similar to those produced by a tube
amp power stage. A modest amount of gain will produce the characteristically "warm" sound of a tube
gain stage. More extreme settings produce harder overdrive.
Judicious use of the LO CUT and HI CUT controls have interesting and subtle effects on the overall sound.
You are encouraged to play with these controls to see what happens. Tightening up low and high frequencies,
in early gain sections can allow you to drive the signal much harder in later gain sections without totally
breaking up. Real amps will usually cut low frequency response at somewhere between 80Hz (Fender)
and 140Hz (Marshall).
General experience seems to suggest that gradually increasing the gain in each section allows you to drive
the signal harder without introducing undesirable effects in the output. However, there definitely interesting
and subtle differences in tone that can be acheived by not adhering to that rule of thumb.
The SAG and SAGD controls the emulation of "forgiveness", and "compression" that are provided in a real tube
amp by sagging of power supply voltage. SAG controls how much
the overall volume of the output decreases as the transform sags. It provides the subtle "compression" that
tube amps provide, which is quite different from the compression provided by compressors. SAGD controls
the amount of additional distortion that occurs as the gain stages receive reduced voltage. It provides
the "forgiveness" of a good tube amp. Because SAGD operates in a feedback loop that runs through
all three gain stages. Increasing the distortion in the gain stages increases the power use of the gain stages;
increasing the power use of the gain stages increases the effect of SAG and SAGD which has an opposing effect
on power use. The net result is that SAGD causes signals to break up more gradually
(hence the perceived "forgiveness"). The effects are non-linear, so not easy to describe completely. You
are strongly urged to experiment with SAG and SAGD settings in order to get best tone results. Use very
moderate settings to emulate tube amp output; higher settings of SAG and SAGD will cause audible compression
and pumping of the outputs which may or may not be desireable.
The TooB Power Stage design is based on an experimental design, that unexpectedly produced extraordinarily
good amp tones. We have not completely explored the sonic possibilities of the
TooB Power Stage. What's known so far: it produces exceptionally pretty clean tones; it can be driven really
hard, and seems to preserve an unusual amount of detail in the signal even when being driven hard; and it
can definitely produce signals that have many of the most prized features of tube amplifiers: warmth, detail,
subtle "compression" without coloration, and forgiving break up.
Explore!
The TooB Input Stage is part of the TooB Amp Emulation Toolkit. Typically, you would
use the following plugins in the following order.
- TooB Input Stage
- TooB Tone Stack
- Toob Power Stage
- Toob Cabinet Simulator
