Blue Cat’s Destructor is a bit different from your usual amp simulation plug-in. Here is video that explains how to understand how Blue Cat’s Destructor works and how to set it up as an amp simulator.
There are three ways to simulate guitar amplifiers, one is recreating each component of an amplifier in the computer, the other is using IRs and the other is shaping the sound with specialized tools according to how it is perceived by measuring tools and the ear itself.
DESTRUCTOR is in the third group. In this video we will try to clear the concept of the DESTRUCTOR interface, especially on what appear to be 3 amp heads in series in the main interface.
