Issues with Cliche

[iandunham]

Hi All,

I'm wondering if someone might provide me with the routing for the switch PCB wires. I'm having some issues with the pcb itself for some reason.

There are 6 wires, I know some other PedalPCB are have the convention like this:



Is that the case of the Cliche?

Another question: I think I toasted the dual gang B50K pot, and all I have around is an A50K single gang pot. I just bridged the two sets of contacts on the pcb, is there a problem with that?

Thanks!

The Kliche uses a B100K dual, not B50K.

You'll need a dual-gang pot, a single gang won't work in this case.

Here's the wiring diagram if you aren't using a breakout board.

Thanks for the quick reply, Robert.

I've now put in a B50K dual gang pot, and wired the switch like above. The circuit passes audio when off, and when on, the dual gang pot behaves in the reverse of how it should: turning it down all the way increases volume/gain, and turning it up decreases the volume/gain.

Any likely culprits for this?

Sorry about that - here you go.

If turning down the Gain pot increases gain/volume the path through IC1.2 isn't functioning properly.

Okay, thanks. Does that photo reveal anything obvious to you?

It looks like you have a few cold solder joints on the dual gang pot. Maybe try reflowing the pins? Robert already mentioned this but your dual gang pot should be Linear 100k not 50k.

Yep, it's a B100K. And I can confirm that there aren't cold solder joints on it.

Looking at the pic and an unbuilt board in my hand is hard to pinpoint whats going on. But do you have a multimeter? If you do can you test continuity between these joints?

As an aside, you can use a DPDT-footswitch instead of a 3PDT for this project.

I find most DPDT switches have a softer touch/better feel than a 3PDT, easier to engage disengage.

Yes, there is continuity between those joints.

Where should I start probing, where the schematic indicates Gain 1 is?
