It has lots of capabilities for tone shaping with its own custom design and internal routing.
There is no line or mic preamp as an input module but INPUT knob will drive EQ circuit's Gain Trim to get nasty op-amp saturation.
Compressor section based on 436c with extra modifications. Compressor has AMOUNT knob to compression and make-up gain. So, it will be gain compensated.
