Neovibe bleed trough when bypassed

[Valoosj]

As it says in the title, my neovibe bleeds trough in the audio chain when it is true bypassed. Is this something that can be helped? Other than this little issue the thing works perfectly. The pcb input is attached to ground during bypass so I suspect that this is an lfo issue.

i would replace the swicth. it might have something in it or it is broken.

Resurrecting an old topic ... I have the same issue with my Neovibe as the OP. It bleeds through when bypassed. I put in a brand new DPDT switch and it's the same. It goes away when I put 'Depth' to 0, though. Any ideas what might be going on?

Many, many ideas about what is going on, but without details of your setup, which version of the PCB, and how you wired bypass, none of them have much to do with your setup.

We need details about what it was supposed to be before we can guess why it's not.

PCB Ver. J 10/07, 2PDT switch wired as per instructions as well as the complete build.

I tried 2 brand new 2PDT switches, this can't be it? I hear it when i run guitar>neovibe>amp and the neovibe is 'bypassed'. If a fuzz is before the neovibe it gets worse.

Did you make your own board from the Geofex information and use the instructions from Geofex? Is this the licensed GGG version?

I ordered the PCB from GGG.

Is it wired per the instructions?

Here's the problem: the instructions show a "true bypass" setup. If it's wired per the instructions for that, it can't feed through. There is no electrical path from the circuit to the output jack.

The original univibe did not do any kind of bypass. It used a "cancel" which only killed the oscillator, making it not sweep.

So - how's that wiring? Does it match the instructions? I recommend printing out the wiring diagram and tracing your wiring, marking off wires with a highlighter pen as you find them correct.
