Phase reversal switch for aby box

[numpty]

Is there a schematic available with component values for a 9v phase reversal switch as incorporated into the parallelyzer ( as yet incomplete)  project which is described on the "general guitar gadgets" site under boosters and routers?

Thanks

No, there's not.

But it works if you use the GEO schematic that the Parallelyzer refers to and make R1=R2=R3=10K and Rbias and Rpulldown = 1M. Cin is 1uF and Cout is 1uF.

The splitter-blend utilizes R.G.'s phase reversal switch and has a schematic with component values inserted.

Thanks to RG and Preston for your help. What kind of opamp is recommended for this circuit ? the "Splitter" has a TL072 but  different component values to what has been suggested by RG. Will a TL072 work equally well in both circuits?

  TL072 is a good choice for dual opamp for that.
  Just about any dual pinout OA chip really.
