Gain acts as a standard gain control, but roll up the amount of Feedback and the Germanium Pre realizes its full potential, as well as adding a small bass boost and a tasty high-frequency roll-off. For cleaner tones keep the Feedback on the restrained side, or crank it up for fat guitars and vocals. There aren't any other preamps like the Chandler Limited Germanium Preamp/DI.
