Looking to cop some raw soul sounds. Stax, Meters, James Brown, you know what I mean. I can cop some convincingly old vocal sounds with an M-Audio Luna, but I'm looking for something that would work well for electric guitars. A ribbon might be nice for that. As for preamps, I'm looking at the Groovetubes Brick and the Universal Audio Solo 610 Tube Preamp. What are your thoughts on these options?
