I would like to put a master volume in my guitar rack between the preamp and amp. What is the best way to do this? Can I add a simple potentiometer?
The reason for doing it this way is that the preamp (sansamp psa 1.1) level is designed more for a studio and doesn't really allow a good amount of adjustment when used with an amp. A master volume would allow me to keep the level on the preamp high and not have to worry about a huge volume increase when switching from one preset to the next.
