Anybody who primarily plays acoustic instruments knows about this preamp and parametric EQ but if you haven't encountered it it's one of the best out there. He makes a lot of studio gear now along with a stereo version of this. I believe this is a late 90s model, I don't think a lot has changed in terms of schematics, and it sounds amazing. As you can see on reverb, they're selling it for more than this, but it does not include the preamp module which is integral to this preamp and not cheap on its own. I own two of these, so I've decided to let one of these go, let me know if you have any questions. Thanks
