Mr. White "Hot Tube Simulator Booster II" (SRV Clean Sound):
Volume control with a small booster "Crank Up" that simulates the saturation valve stage of the Fender Vibroverb, Dumble, Bassman, Super Reverb.
It is a special pedal for lifting guitar solos or simulating the tone of a valve amplifier with the vacuum tubes to the red and blue.
Stevie Ray Vaughan used a very warm sound and very bright and even mids harmonics on the guitar to be clean and had no effect. On this pedal you can get this tone with no problem and there's no need to put up the gain to achieve that unique sound.
Controls:
Crank Up: is the knob that switches the "Drive" which gives the saturation sound.
Master Output: volume knob or exit of saturation.
