Re: NU Tube Tube Screamer
It runs the tube at 30 volts, which is a 'starved plate" design.basically juts a tube inserted into the circuit instead of a silicon diode. Correct me if i'm wrong. This is an excerpt from a discussion about it by "Phil", I'll have to look to remeber what company he represents, but it's a famous company;
"Normally, a 12AX7 tube is run with 100-200V on the tubes plate terminals for clean amplification, lowering the plate voltage to 30V starves the tube of the regular flow of electrons and causes the tube to readily distort. Tube distortion produces pleasant sounding even harmonics, contrast that with the scratchy odd-harmonic distortion (often called crunch) that comes from transistor/diode distortion circuits. Tube distortion tends to make more of a howling electronic sound that is commonly heard in late 1960s / early 1970s rock-n-roll recordings. A good example of the tube distortion sound is Eric Clapton with Cream playing "Sunshine of Your Love". Producing tube distortion in a starved tube circuit instead of an overdriven tube guitar amp has the advantage of making good tone at much lower volume levels."
There are some OD's with tubes in the circuit that run at high plate voltages- Duncan made some in their "classic " series, and HT Blackstra i think, as well Vox, I'm not really sure.
