After years of using budget pre's and being disappointed with the constipated guitar tones, I finally bought a decent mic pre. My guitar sounds like it does in the room. It cuts through with all the harmonic content. Kick drums sound big, bold, and articulate. Overheads are crisp without being strident. I can actually hear the presence peak in an SM57 when that mic is on my guitar cab. And best of all--little or no EQ is needed during a mix. I'm really digging this thing. It's definitely not a "character" preamp, but it delivers clean, accurate sounds to tape. At $800 or so for 4 channels, this thing is a steal.
