VL20-DC HighTone

VL Effects VL20 Double Channel HighTone

FEATURES

What are some common design elements make a clean amp sound clean?

  1. Fixed Bias—most really clean amps are fixed bias. This gives an amp a firmer bottom end and more clean headroom.
  2. Higher Plate Voltages: Higher voltages on the plates of the power tubes reduce the midrange and breakup latter than lower plate voltages.  For example a Fender Twin Reverb (the prototypical clean amp) runs it’s 6L6GC’s at ~460VDC while the Fender 5D4 Tweed Super (lots of bluesy breakupand midrange) only runs it’s 6L6GC’s at 360 VDC.

BIAS setup and Dynamic Clean Tone

Setup bias for each power tube in order to martching both output tubes with perfect current plate

VL20 Clean amp sound, headroom, dynamic and overdrive:

  • Bias : Fixed Bias-This gives an amp a firmer bottom end and more clean headroom.
  • B+ : Higher Plate Voltages: Higher voltages on the plates of the power tubes reduce the midrange and breakup latter than lower plate voltages.
  • Tone Stack : Positioned early in the circuit that scoops out midrange.
  • Headroom : The VL20 HighTone is very dynamic with high headroom. Loud clean tone and easy to overdrive. It is unique for an amp to have both
