OK, so I got a REV2, and I've been curious to try something. If you want your REV2 to sound more, well, "analog," try running it through some transformers. Holy crap, this really works. OK, so what I'm doing isn't cheap, but I already had this stuff "lying around" so I thought I'd try it. Run the REV2 into a Radial JDI Duplex to get it down to mic level (transfomer #1). This first transformer will not alter the sound much. Then run that into a Great River MP-2NV transformer-based mic pre. The secret is to drive the input transformer (transformer #2) until you've achieved the desired level of analog-ness, while turning down the output transformer stage (transformer #3). By adjusting the input and output gain you have complete control over the level of analog-ness. This kinda rocks and will be used a lot during tracking. It takes a sound that's kinda plastic to something very organic. A filter sweep on a bass sound like F1 P101 is a creamier, less buzzier affair. Yeah, filter sweeps are much nicer now. I'd love to find a cheaper permanent option to attach to the REV2, not sure what it is?
