Getting ready to record some tracks and have some options. Here's what I have: SM57 Audix D4 (have mic set for drums, heard D4 was best for bass) Ampeg SVT-II DI GT The Brick ART MPA Gold with Ruby tubes Presonus FP10 I'm thinking of recording 3 tracks: 1) Brick --> interface 2) SM57 --> MPA --> interface 3) D4 --> MPA --> interface My questions are: Is the brick an improvement over the SVT-II DI? Is the Brick an improvement over the ART? Should I even bother with the SM57? Should I use the ART for the mics or the Presonus Pre's? Oh, I'm using US Fender Jazzes (Standard with NJ4's and '06 Deluxe) --> SVT-II --> Berg NV610. We play Rock, think Black Crowes, Zepp, ect... Thanks for your help!
