infinitely richer and sweeter. An overdriven signal can be achieved by significantly raising the level of the drive control. This overdriven tube effect is extremely useful in providing distorted guitar and for creating that authentic “blues harp” vibe (harmonica). The possibilities of the drive control are limited only to your application and your imagination.

Gain

This control governs the amount of boost to the signal being processed by the preamplifier. Dynamic mics and instruments without preamps normally require more gain than condenser mics and instruments that have a built-in preamp (care should be taken with instruments having their own built-in preamp not to overdrive the input of the TubePRE). Increasing the gain should provide the signal that is needed from the preamp for a hotter (louder) recording level.
