Warning about VFE switching PCB (Use the correct RELAY.)

tfl;dr:
Be careful when subbing out similar relays. Don't use a "2 coil" relay.
Nothing bad will happen, it simply won't work.

Simple version: don't use the series with "L2" in its name.
I tried Panasonic TQ2-L2-5V, when the correct relay was out of stock,
and it didn't switch. (Actually, it would switch between effect and silence but never dry bypass.)

I swapped the relay with the specified TQ2-L-5V
and it works great! One "L," not two baby.

And that's the only thing I changed so I'm pretty sure that was the culprit.

Captain Obvious, out!

I just did the same thing and couldn't figure out why I couldnt get a clean signal. Glad I found your post. Just ordered correct relays.

Glad it could be useful!

I should mention, on this particular pedal, the LED comes ON when the pedal is OFF and OFF when the pedal is OFF.
Probably not related to the relay issue, but I figured I should mention it in case you experience something similar.

(In my case, I think it's because I used a PEDALPCB main board with a VFE relay bypass, and I probably just wired something incorrectly.)

The ONLY saving grace with these relays is that they're relatively easy to desolder and still work.

Don't ask me how I know...
