I am currently using a Groove Tubes GT55 and some scattered Oktavas along with a Tube MP preamp. I've heard people diss my preamp before. How much does a preamp affect the total sound of recorded vocals? What preamp would you suggest withing the $50-$200 range and how would it benifit me? My man goal is to get my vocal tracks to sit better in the mix. They tend to sound more like a voice over (which is why i got the GT55, sweet mic). Thanks all!
