Thank you, Lucifer! It's true what they say: The devil is in the details. :twisted: That is a strong possibility, but I can't find any conclusive info to know for sure.

Tropical Fish caps with SIX color bands?

Is anyone familiar with Mullard C280 tropical fish capacitors that have six bands? Mullard datasheets only show five color bands. I'm looking for a color code chart to identify the following color sequence: brown, black, orange, white, yellow, brown. Normally I would call this .01uf 10% cap, but the...

Re: adding a switch to go from positive to negative ground.

I wanted to update everyone reading this post that the switch works perfectly. It functions exactly as I intended it to, and the bicolor LED was the perfect solution to having a polarity reversal with a DPDT switch, while enabling me to have a visual indication of polarity and status at the same tim...

Re: adding a switch to go from positive to negative ground.

Thank you for your replies! The bicolor LED solution is pure genius. Thank you to earthtonesaudio for your insight as well. It's funny that you mention 99.9999999% of all circuits, because this pedal is one in a million. Once I release my pedal to market you will understand why I wanted to have feat...

Re: adding a switch to go from positive to negative ground.

I'm not quite sure what you mean by always having the same power supply. So when you are in the positive ground position, its the exact same setup as a pnp fuzz wiring scheme. When you switch to the negative ground position, then it's the same wiring scheme as npn wiring schemes found in most effect...

Re: adding a switch to go from positive to negative ground.

I just want a switch in my pedal that will switch the pedal from positive to negative ground. Normally a pedal is wired for one or the other, and I want a switch so the pedal is wired for either at the flick of a switch. I don't know how to accomplish this while still getting the LED status to work ...

Re: adding a switch to go from positive to negative ground.

I haven't thought about that. I was just hoping somebody could help me figure this out. Thank you for taking the time to reply to me.

Re: adding a switch to go from positive to negative ground.

There is no caps or anything else in the circuit to change the polarity of. It's for a new pedal I'm bringing to market. Pretend there is no effect circuit to worry about. Is it possible to do this while also switching the LED? I imagine a dpdt switch would do the trick without the LED, so perhaps i...

adding a switch to go from positive to negative ground.

This is my very first post, and I am looking forward to opening a dialog with the freestompboxes community. My question is: What is the best way to add a switch to change a pedals power from a negative ground 9V supply to a positive ground 9V supply? I would like this to be incorporated into a 9V ba...
