I bought a Kern IP-777 from fourstring44 last weekend, and got it today. When I bought it, I wasn't particularly looking for a preamp, but I don't think I've seen them sold used before, so I figured I'd jump on it. So this is what happened when I got it home- I have a Peavey TKO 80. My Mesa is at my friends house, and I didn't get home til late anyway. So I plug the Kern into the "Power In" patch on the front of the Peavey. I turned both on, and I wasn't really impressed. It just sounded like the Peavey always did. So I tried recording it. I ran the Kern into my MBox, and recorded some stuff. As I recorded, I was hearing mostly string noise, as I was digging in, and the stereo wasn't that loud. So again, I thought, not a whole lot of difference, maybe I shouldn't have bought it. Then I listened to the playback. I don't even have words to describe how good it sounded. It's the tone I've been seeking for months, years now. Just a sick sound from it, nice tube grit. I haven't even played with the EQ yet, it sounds great flat. I'll see if I can post some sound clips.
