Tweakingmodules
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 buons on the front of the module. In an eort to explain the Tweak
mode in ReValver, we’ve wrien some short explanaons of each tweak in the tube tweak GUI.
TheTweak mode in ReValver was wrien on an engineering level using real schemacs by a real tube
amplier company, and it takes years to learn tube amplier engineering, so the awesome “tweakability”
of ReValver MKIII will keep even the most experienced valve amplier 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 ampliers
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
dier from module to module. Some features include Frequency Analyzer, Oscilloscope, Total Harmonic
Distoron analysis and save Impulse Response.
The FrequencyAnalyzer runs a frequency response test of the module in queson. It does so by
inserng 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 distoron 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 resoluon. This emphasis can be adjusted via the slider at the boom of the win-
dow.
