Unverify this.

Just made it and all i get is a non-stop "beating" sound no actual gtr signal going thru.
Or am I just missing smth here?

I didin't build it not compare it with the schematic, but it says verified.
Anyway, pay attention with this layout. To make it "mini" it has some unusually cut track between holes and an holes shared between a lead of the cap and a jumper.
Did you check every components and cut track... and all the rest?

Yes, Sir. did the tracks (genius way of cutting it to save space imo) checked it all

Ok. Keep to check your built, I'm going to compare this layout with the schematic and the bigger layout
in case there's something wrong. Maybe the author built it succesfully but he posted a wrong version.

Ok, I think I found at least a mistake.
Did you see that cut track line next the 10nF? Jumper it, because that 10nF should go in the VB right in that stripe, instead now is isolated. But I think that is not enough to make the circuit mute, it controls just the high end cut.
I can't find anything else to make this layout failed. Anyway, fix that and test it.
If it still doesn't work... I'll write here the usual thing to check, just in case:
Position of the components, position of the wires, orientation of the caps, orientation of the diode, check if the pot works, check the jack connection, caps value, resistors value (compare the bands color with the resistors you have in stock).

If you want write the votages of the IC (is it a LF442?), and maybe you can post some pictures of the circuit.

Are you testing the board or is everything into the box?

Hey!

Out of the "not wantingness" (I know that's not a word lol) of building another one (since I rly enjoy the non mini version of this in one of my guitars) I decided to give it a try by probing it and the mistake was just at the very beginning (47n Cap was placed 1 space off). Well, I should next time do my work properly rather than spew nonsense.
So, sorry about that.

Now it works well and I am looking forward to putting this into my 2nd instrument now.
Thanks for the help!

Great! Thanks for the update.
Did you jumpered the cut track next the 10nF cap I mentioned some message above?

no, mate. the jumpering wasn't necesarry

I may give this one a go. When I do I will leave that cut out. Makes sense.
