Hi, I'm looking to lay down some nice quality bass, guitar, and vocal tracks. I was using SM58s for a while just to demo and recently I've begun to hate the sound, as I am trying to add a more "organic" element to my electronic music. I purchased a presonus tube pre and with an sm57 it is really an incredible improvement. However, using the unit as a DI box the bass is noisy to the point where it's unrecordable. My question is, should I ditch the presonus altogether and get a nicer preamp, or get a preamp just for bass guitar. I don't have a large budget but if it is worth it I would be willing to spend more. Everything is going into a tascam fw 1082 into logic pro 8. Thanks in advance!
