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.
