MXR Blue Box w. mods

 Couldn't resist to add another layout for the Blue Box since there is a bunch of mods online...

  • Octave switch that toggles between stock two octave down setting and one octave down setting.
  • Treble boost switch that lifts up 10nF low pass filter cap before the Output control. Should result in an overall brighter and louder tone.
  •  Both potentiometers is increased from 50k to 100k. This is supoosed to increase the overall output.

 One untested mod that could be fun to try out would be replacing 330ohm resistor that sends voltage to the CD4013 IC with a small value potentioeter for a starve control since those chips can behave quite funnilly at different voltages.
