Vacuum tubed tone control???


Hello, I was wondering if anyone has manufactured a tubed tone control that could be put in-line between a cd player and preamp? I was hoping to add some musicality by rolling some NOS tubes into it, hopefully without hurting resolution too much.

Thanks, Joeylawn. I ordered a T1951 (great deal on a refurb at Musician Friend with a 45-day return option). I will post my impressions once I've used it a while.
btw, i have a pse hl-1 in near new shape... the tone control is called a tilt control... let me know if you are interested
