| I have a Goodrich L120 volume pedal that is begining to have a dead spot in the pot. What is the best pot to buy for these, and where would I get one? Would a squirt of electronic cleaner or WD40 help it? I’ve never had any trouble with a volume pedal before. |

| Assuming you have an older style pot (Allen Bradley, Claristat), you are experiencing a typical problem with pots. You can try a good contact cleaner, and it may give you some temporary relief. This would be a good time to consider replacing the pot with one of the new Goodrich pots. They have a life expectancy that's greater than the old style pots and they're extremely quiet. If you pedal has some age on it, replace the string while you're at it. Contact Forum member Bill Ferguson. He can get you going with the pot and the string. |

| Thanks Roger. This volume pedal is about 18-19 years old. My old Sho-Bud pedal still has the origional pot. I’ve just never had to deal with replacing one. |

A cleaner-lube made specifically for volume controls or faders may help. (I use Deoxit F5) For best results, you'll have to remove the cover from the back of the pot, replacing it when you're finished. Remove the cover, spray the pot liberally, and then work it back and forth very quickly 20-30 times.
Don't use WD-40, it's not made for electronics. |

In my shop I had for 30 years, both on customers, and my personal guitars, I used WD-40. Didn't know any better. It always did the trick. No problems. Getting it in to the wipers of the pot can be hard. I actually drilled a hole in the back cover of an old Sho-Bud Vol.ped pot once and shot in some WD-40. Worked great. It's not made to be a lubricant. RP

Jack, I will be happy to send you a new volume pot and instructions or if you want, you can ship me your pedal and I will install a new pot for you.
Yep, the old Allen Bradley pots of yesteryear lasted a long time.
Then we went through a spell of really bad pots.
Now we have the new Genuine Goodrich Volume Pots that are seeming to last like the AB pots did.
You know how to reach me.
Thanks,
Bill

Thanks everybody! This Forum is great.
Bill, I either get a pot from you or I may just send you a couple of pedals. I took an old Sho Bud pedal apart for a drafting project I did back at Dekalb College about a hundred years ago, and you won’t believe it........yep, it’s still in a pieces in a grocery bag! If I can find it. I’ve given myself about 43 years to get it back together. I guess that’s about long enough. |

Hi all. I'm now offering a new style pot that is formatted like common pots (3 lug side-solder)r. It is the same 470k pot, built by the same manufacturer and guaranteed for a million cycles (although I suspect they will last longer than that!). The only difference is the placement of the soldering lugs, which makes it easier to attach the wires. Check it out at
