Hi (beginner here): I'm recording a guitar amp. I'm using a Rode NT1 thru a Peavey VMP2 pre, right to the interface (Audiophile 2496). But as I turn up the volume I get the interface input overloaded, even with the pre -20db input pad enabled. Do I need to get into a console after the pre in order to attenuate the signal? Thanks in advance!
