i currently have the non tube b-52 half stack and a jackson dinky

i am looking for a preamp to add to my sound

what do you guys suggest for giving a clean bottom end with tight mids, but still some ear shattering highs...

the b-52 gives me some pretty damn good lows but i need to accentuate the highs more?

i know im probably not making sense but hey im trying.

also it must be all tube so i can play with the sound a bit.

and i can't afford to spend more than between 200-400

edit: note this will be coupled with a DOD 231QX
