Peavey ReValver MK III - Tweaking Modules

Tweakingmodules
One of the most powerful features of ReValver® MK III is the ability to tweak each parameter of a module
other than the usual knobs and buons on the front of the module. In an eort to explain the Tweak
mode in ReValver, we’ve wrien some short explanaons of each tweak in the tube tweak GUI.
TheTweak mode in ReValver was wrien on an engineering level using real schemacs by a real tube
amplier company, and it takes years to learn tube amplier engineering, so the awesome “tweakability”
of ReValver MKIII will keep even the most experienced valve amplier engineer busy for hours. Users who
don’t have any experience with tube amps will have fun, and you’ll learn a lot about how tube ampliers
work.
Press the “+” bu on on the module, or select “Tweak Module” on the module menu to bring up the
general Tweak GUI. The Tweak GUI is a general GUI that holds specialized tweakable components that
dier from module to module. Some features include Frequency Analyzer, Oscilloscope, Total Harmonic
Distoron analysis and save Impulse Response.
The FrequencyAnalyzer runs a frequency response test of the module in queson. It does so by
inserng a short “pulse” and performing a FFT (Fast Fourier Transform) frequency analysis of the
out put. Please note that such techniques may not yield expected results in non-linear modules
such as distoron modules. The Frequency Analyzer also accurately displays the phase response
of the module. The analyzer window is displayed in logarithmic mode with the lower frequency
shown in high resoluon. This emphasis can be adjusted via the slider at the boom of the win-
dow.
