Hi, I'm looking for a decent budget preamp. At the moment it's between the Presonus Blue Tube DP(2 channel) and the Studio Projects VTB1(1 channel). I would be using it for mics and instruments, such as bass. The 2 channel thing isn't essential though it could come in handy. I really just want a good sounding pre. Anyone any experience with these or any other pre's that may suit me?
