The Red Dirt Germanium is nothing short of a red hot saturation machine. Perfect classic amp tones. The new mod happened as a result of Robert trying to be a touch lazy. Or let’s say, he was trying to find a short cut and struck gold. In modifying the circuit Robert came across a way to have variable gain on different parts of the frequency response. The resulting sound is exceptional. It sounds 3D. It’s more of everything. It in fact cleans up really nicely with the volume control even though it has plenty more gain on tap. It makes a stock screamer sound very flat and one dimensional. By allowing differing gain rates for the bass response, the bass stays tight and forceful. The mid range and highs are soaked in sustain and saturation. The balance is exceptional.
