Hey, I realize the R121 needs plenty 'o' juice to be happy. I've been pairing it with an Amek 9098 pre/eq (up to 72db gain). I've noticed w/drums & loud guitars (if up there in volume) I don't need the higher gain so much. Would you recommend using the high gain pre only when needed??? And anything goes for louder stuff??? I've also got an Avalon 737sp and some Manley pre's to fool around with. Any noted 'favorite combos'??? Are there some 'magic' pre's that the mic loves??? Thanks in advance.
