Wondering if I need to purchase 2-2 channel mic pres or 1-4 channel. I am looking at the Sebatron VMP 2000e and RNP (or similar) or the Seb VMP 4000e. I did not know if recording all tracks on the Seb would create any problems, frquency wise. I have read that using a Neve 1073, for example, for all tracking can create some build up of certain frequencies that may not be desirable. Currently using a Langevin DVC and will probably sell to purchase the other pres (I need 4 channels of preamp). I do not want to trade down by going to the Sebatron or Seb/RNP, but from what I have read about the Seb, I doubt that will be the case. Oh yeah, I am recording acoustic type music (folk/bluegrass/etc.), am I looking at the right pres for this kind of work and budget (+/- $1,500)? I am using Soundelux U195, Josephson C42, Oktava MC012 and At 4041 microhones. Thanks. Tim T.
