The cool thing on the Pharoah is switchable. You can go from germanium to silicon. or none (which has a really big boost in volume, make sure you start your amp very quietly if using no diodes)
My usable setting is almost the exact opposite of what Sam had it set at with his gear (the gear you have now will play a major role to the end tone of this pedal).
It get's a little muddy, but it is really gutteral. Me gusto.
That El Raton has a diode lift on the hard clipping side (Classic Rat and Turbo Rat) and also on the soft clipping (Germanium and Mosfet), and man those diode lifts do boost the volume, and actually sound great too. I am surprised how good just the basic GGG green Russian clone sounds on bass though, and killer on guitar. Would love to hear a Rams head version too. Might buy one of the GGG rams head kits to fool around with down the line.
