The Scream is a very detailed discrete component model of the classic green Tube Screamer pedal. It has input and output class-A transistor buffers, Boyle macro modelled op-amps, and a selection of fully customisable clipping diodes. In fact every value of every component can be changed and randomised to customise your tone. Choose from a selection of diodes including silicon, germanium, or LEDs to create asymmetric clipping combinations, chain any number of diodes in series or even bypass them altogether and have a high gain boost that then clips the op-amp.
