A perfect emulation, it sounds analog, it sounds fat, it sounds creamy and very 80's, anything that I throw the improvement, open sound, highly recommended to use in the master of the DAW, congratulations for having created a plug-in created a plug-in that will shine for a long time. In regards to this emulation, the term "magical" seems to be appropriate. There's something about a Rule Tec Heritage Pro that enhances anything you run through it, even if you don't apply any EQ. There's a glow that happens within the tubes and transformers that adds some weight in the low end and opens up the top. Amazing piece of software.
