Minitaur Switch wiring

[Droogie]

Went to test out a Minitaur on a great board from Pickdropper. I thought I had a handle on the switch wiring but get nothing in either bypass or effect on. I wired the switch thusly from the numbered pads on the pcb:

1    4
     68k
2    5
     68k
3     6

And conncected in from the pcb to in jack, out from pcb to out jack, 9v and gnd as per usual.

I checked continuity and the switch does move between 1–3 and 4–6.

Any ideas what I'm doing wrong?  Thanks!

I probably should make a wiring diagram for that one since it is not the standard True Bypass wiring.  It is, however, the standard Klon wiring.

From what I can see, you wired it right.  Did you wire the ground connection to the input jack?  I assume you did, but I don't see it listed below.

Pictures of the 3PDT switch might help as well.

Also, is there any possibility that the 68k are a different value, like 68 ohms or 680 ohms?

Since I was using my test rig, no jacks involved. It's going into a multi build. I'll just hook it all the way up, jacks and all and see if that does it.

That's a good idea.  Please let me know if that solves it or not.

Evidently it's not just the switch. I get a high pitch whine with the gain control at 7 o' clock; the volume  and tone controls have an effect on this sound. I'll do the usual troubleshooting, i.e., check values and soldering.

Hello @Droogie,
A bit of a longshot as this is such an old topic but, did you ever get your problem fixed, I seem to be getting the exact same problem...  High pitched whine, some oscillation interaction with guitar signal and all controls seem to work as they should, most certainly too much gain and it's rather spluttery...

Cheers

Does it happen with
A)no guitar plugged in
B)as the only pedal in the chain
C)with a dedicated power supply/battery?
If it's happens in all three of those instances, it's either the board or your wiring.
If it only happens when not on a dedicated supply/only pedal, it's probably the charge pump interacting with a other charge pump that operates on a similar frequency.
