So I’m about to wire up a modified version of the old Supro Coronado and I’ve got a few questions. I’m only building the Trem channel, without the actual Trem. First, is it safe to omit an input resistor? I thought I read something about problems if something failed and shorted. The Treble input does not use an input resistor, though it uses a capacitor. I’m not married to this schematic, I plan on making several changes, but I am interested in trying to keep the overall sound.
