Most of the crowd will advise you against a cheap "tube" preamp, stating things like the tube doesn't do amplification and it's just there for effect. That's true, and I used to say the same things. When I first started I got an ART Tube MP and hated it's dark sound, and started searching for more "transparent" preamps.
Yeesh, when it comes to vocals and acoustic guitar, I now prefer the dark & dirty sound of the ART compared to more "transparent" preamps. Yeah it's an effect, but IMO a good one. Ed told me I'd feel this way...he's always right...the bugger.
