I'm running KX 3539 on a SB Live card. Absolutely love it. Recordings sound professional and reproduction crisp and clear. I use (on the DSP module) an effect (EFX Tube drive) to record the E. guitar. It sounds great and very flexible. My question is, does anyone has or knows of a similar effect for microphone input? I use a pair of fairly good mics with wide diaphragm but the tracks laid out either on Sonar 7 or Audition 3 sound lifeless. I mean very digital with a total lack of harmonics. I understand that this issue can be solved by purchasing a tube pre amp. Right, but on the other hand the EFX tube drive makes my ax sound as if it was plugged into a Marshal rack. Must liven up vocals to sound pro. Please help!
