Valve Wizard Flanger

Mixing it up and doing Flanger Friday this week. Got a request for this circuit designed by Valve Wizard. It's unique in that it uses 2, PT2399 delay chips paired with an LFO. It features a buffered bypass, so it's not a true-bypass effect. I've also drawn up daughter boards for the bypass switching (PCB version has the footswitch board mounted). Here's the schematic for reference. You'll definitely need a 1590BB enclosure for this one.

  1. It does have that PT2399 sound somehow, but really cool use of the chip regardless.

  4. Do you have the schematic for this flanger?

  5. I think that this circuit have a detail in the pin out of the 7805 the configuration is pin one in of voltage pin two is gnd and pin 3 is output of voltage (5v) but in this layout the pin 3 from 7805 is in

  6. Что бы начал работать генератор, необходимо на 2 ногу потенциометра RATE подать через резистор 300-400 Ом напряжение в 5 вольт (от ноги 1 потенциометра Depth)

    1. И вместо конденсатора 100uF в LFO, поставить около 1uF не полярный конденсатор.

    2. So, translating this text with the Google Translator it says that the LFO's 100uF cap should be replaced by a 1uF non-polarized cap.
      And it is necessary to apply a voltage of 5 volts (from the Depth's pot leg 1 o) through a 300-400 Ω resistor to the Rate's pot leg 2.

  7. I do not see rate 1. Only rate 2&3. Where is the position of rate 1 for pot.??

  8. I have build this.. but it does not work well no flange. Just a clean sound.. can anyone help me.??
