Hello, for my first post , I'd like to ask a question. I'm wondering what a good mic pre for recording drums is. Right now I use a four channel sytek non-tube mpx 4a(burr brown option on channel 3, 4). I want to know if I should look into getting a nice (1-2k ) tube pre, like sebatron vmp4000. I use : -beta 91, kick inside drum -akg d12, kick outside, batter side -beyer dynamic m201 , snare -cad m9 overhead, or aea ribbon r 84 overhead. The sound is good for now, and for the music I make,, but I'd like to tweak it as much as possible, . Wondering if a nice tube pre would add some needed character and interest to the sound. Suggestions on good multi-channel tube pres for 1-2 k?
