So i just bought the Navigator yesterday, EVERYONE and there mother said it was an awesome pre-amp. but so far my Sansamp R.B.i is making this thing look like a cheap P.o.s. so i think something is wrong with it. its clipping my pre-amp and not producing much Sound, its like everytime i strike the string it Clippes HARD. . . and the sound it does make. . . sounds terrible. i think its prolly my pre-amp tubes? is that possible?
