Anyone know of a PNP Fuzz Face negative ground vero layout?

Anyone know of a PNP Fuzz Face negative ground vero layout?

there's gotta be one here

Yeah they'll be one somewhere on the Internet. I have tried searching but I haven't found one yet. I'll keep trying but if anyone knows of a link or has a layout they would be willing to share, that'd be wonderful

Cheers

You need to be aware that using a PNP fuzz face circuit with reversed power and ground sometimes causes intractable noise and/or oscillation. It may work - or it may not. We regularly have people here asking why their PNP fuzz face with inverted ground oscillates.

The cure is to put it back to positive ground.

Thanks RG

I've been reading some of your other replies about the subject.

This must be far to easy to work but...

Could you wire a PNP face fuzz as normal but flip the power supply socket so the positive goes to negative etc and use it with other neg supply pedals?

Cheers

I've got an answer for you... i've got a Vero layout with on board pots (PCB mount type) to fit a 1590B that has a MAX1044 on board to convert the power supply.

Interested?

I would be!

Using a power converter on the board is a great solution!

[rosscocean]

Yeah that'd be great

[joegagan]

using an ultralife 9v with 1200 mah rating is a darn tempting thing too.

[Scruffie]

Here we go, I wont say it's an easy or the cleanest build/layout but thar be the limitations of packing vero layouts in small spaces.

It's for using a battery, look up R.Gs article on Geofex about using a MAX1044 for bipolar power.

Thanks for sharing scruffie

did you actually click on the link I gave above?  here's the first pic:

[rosscocean]

Yeah I did. I was looking for the standard fuzz face circuit but I might try this one.

Ah! I see, read it. I might have a go at that, seems like a better idea than the diode on the power line to ground. I use the 7660 for charge pump and polarity swaps - cheers!
