Hi gang I could really use some help.

I've recently built my own fuzz units. Two of em. One of em is your typical fuzz, all blistering and fuzzy. The other is a lot more subtle. The fuzz is still there but a lot smoother, less aggresive, more like a drive.

So what I need is a rough drawing of the volume pot. I want to use it as a blend control, rather than a volume. To blend the effected sound with the unaffected sound So for example far left is like the effect being off, far right is like the effect being on. Inbetween is any concoction of the two sounds melded.

Can anyone with a bit of a clue about electronics knock up a rough sketch of how to do that?

Would be glad to help here, but I don't have a means to post pics at the moment, I kinda think you need a blend pot for simplicities sake.
I did this on my classical guitar so I could blend to separate pickups going out to amp.
A third pickup for my classical is being investigated with the possibility of 2nd blender.

On the other hand it almost sounds like you're talking Y splitting the two pedals.
IF so, Y input and Y output may be the thing your thinking of.

Guitar to Y splitter (one into two), Fuzz pedal A left, Fuzz pedal B right - a vol pot after each pedal then Y splitter again (two into one).
That "might" work.

Ah thanks for the input mate.

So I need to look at a blender pot schematic and adapt that to my pedal.
I don't think the Ycable idea is applicable here, though I see how that could work too. Infact just thinking of a split cable (two Y's in and out the pedal with one side being constantly connected) gives me a good notion on how to do it.

Thankyou once again. I've adopted a self teach method to electronics. Dive in head first then work out what happened when the dust settles.
