I'm thinking of buying a golden age pre 73 Jr. The present on my firestudio project are way too clean for my liking.
I have tested out a external preamp before using the line inserts on the combi inputs of the interface but noticed the the gain knob still affected the signal. Should this not be completely bypassed if using a line signal?
Would it be ideal to leave the gain knob at zero and the signal from the mic preamp alone?
