I've been trying different pots in a pedal
Goodrich 500 k ..,Dunlop hot pot 470 k
And some 250 k pot ..
They all sound different ..Some don't get full body till wide open
So what's up with the pots ?
And body have a complicated or simple explanation ???? |

Are you setting them up for full on?
Because they're using different media for the resistive track, it makes sense that they color the tone.

| I believe that the point Lane is making is that normally the range from full on to full off on many pots will exceed the sweep of most volume pedals, so when installing you have an option. I prefer to have the pot set full on so that there is a slight bit of volume remaining when the pedal is completely disengaged. |

Philip, in order to protect pots from the force of your foot overpowering the stops inside the pot (Hint: foot wins), EVERY pot pedal out there gives less than full travel. This is NOT a design flaw, this is to protect the pot.
So when you string it up, you can choose to have it either:
Wide open (or nearly so) when "floored", but not shutting all the the way off (often not even close), or;
All the way off when "heeled", but won't open all the way (hey, we run through 300W amps that we set on 4, we don't NEED all that pot), or;
neither all the way off when heeled nor all the way open when floored. This is probably the safest, allowing for a margin if the string slips.
I suppose there ARE other ways to wire them, but sleeves to one terminal, input tip to the other terminal, and output tip to wiper.

| I've been using the newer PEC lifetime or 1 million cycle pots and the sound fine but the million cycle thing is a joke. I bought two two years ago and one is scratchy and I've been looking for a replacement. I have two of the Dunlop pots and these things are just way to bassy for me. I tried reversing the wires and they sound the same so I'm still looking for something that works. If anybody knows of a decent pot that isn't bassy and will work in a normal volume pedal please send me an email because I don't check in here very often. |

Frank, I agree with you that the one million cycle thing is very far fetched but as you are aware I sell them and I use them in my pot pedals and I have very good luck with them. I am careful when installing them to make certain the pedal stops the travel before the pot bottoms out in either direction. Also, a pot pedal needs constant use and not be allowed to sit in one position for a long period of time which can cause a corrosion spot where the wiper sits especially in high humidity environment. I really don't think two years is all that bad for a pot to last. I am afraid there is no pot currently being made that can hold up like the AB pots we had back in the 60's. I also sell the Dunlop pots and find them to be good also. I just find them not quite as easy to install as the PEC pots. You should not be having a muddy tone from them if wired correctly. I am sorry the PEC (One Million Cycle) pots did not please you.
Jerry
