Relay switching with a positive ground Fuzz Face?

[albinalbinj]

Hi,
I'm thinking about building a Fuzz Face with a relay bypass. I will use the Latching Relay circuit from PedalPCB. Can this be a problem? Can the 555 introduce noise or make the Fuzz oscillate?

Also, can the 555 be substituted with a 7555? Is this a good/bad swap?

Thanks

I'd recommend using a voltage inverter to do this.

That way, you've got bipolar power supply. Positive ground side feeds the fuzz face, negative ground feeds the relay bypass.

That's a pretty simple one right there.

Thank you! I forgot to add in the OP that I’m planning on using an LT1054 to invert the voltage, but do you think it will work without any issues? I don’t think I’ve ever seen a fuzz with relay bypass
