Hi,

While searching for treble booster schematics, I've found this :


But my knowledge in electronic is poor, as my english!
I'm not used to this kind of schematics ; I don't understand where is the "mass" (?) - negative point - of this circuit.

Could someone help me to redraw it in a much "complete style" with a true bypass switch (stompswitch?), a 9v dc jack etc. ?

    ...Notice how the pre-voice circuit [pot + HP filter cap] was added to
make the schematic shown in first post.
  By comparing the two schematics, how the adding of TB switching was done should be clearer.

What does it mean "positive ground" ? I have to connect what is symbolized by triangles to the positive pole of the 9v battery ?

  Did you look at the GGG circuit diagram ?
   http://alltransistors.com/transistor.php?transistor=44601

  The diode points from E to B in a PNP transistor, the circuit must follow the transistor polarity. Use DMM to test continuity between the points marked as 'ground' [ie we're building a +gnd circuit] and what will connect to the battery + pole.
