What's the latest on goodrich pots?

Logan Day · From: Washington, USA

I recently purchased a used Goodrich pedal, and I'm interested in replacing the scratchy pot that came with it. Many older posts I have come across recommend the dunlop Hot Potz 2, but I have noticed the design has changed recently, with the older round model being out of stock just about everywhere. The only amazon review for the new one claims that the pot only reads at about 440k. Most folks in older posts recommend the one Tom Bradshaw is selling, but judging by the product photo it looks like he also may have switched to the newer model. Does anyone have any insight on this? Is Tom actually shipping the round model, and does he actually modify the pots from dunlop? Have you tried the new one? Have you had success with other replacement pots recently?

Thanks everyone!

I have not used the 2nd gen. Hotz Potz but I have installed a half dozen or so of the 1st gen. I suspect they are the same 470K ohm electronically, just the shape and tab config.

This most recent model looks like an improvement over the older one having the terminals moved to the more traditional config.

The older ones with the little buttons on the back were just a PITA to solder on, plus clearance from the pedal housing needed to be checked....close on my pedals.

You'd have to check with Tom, but I don't know that he does any mods to them.

Both of these models have the flat milled on the shaft which makes adjusting the pots starting/stopping position difficult.

If you check with the Goodrich folks, I believe those have a completely round shaft. Not sure about Tom's.

Overall, they work fine. I would still prefer the old AB pots but they're history, so these are what we have to work with.

The taper is slightly different on these, but once you get used to them, it's fine.

The only difference in the original Dunlop audio-tapered pots I originally sold and the ones I now sell is the style of the soldering lugs. The older model was a bit more confusing with the "stud-projecting" soldering post model. The current pots have the more standard soldering lug configuration. The "guts" in these pots is the same and are lasting forever it seems. Good for buyers, bad for sellers! And yes, they are 470 ohms. ...Tom (tommybradshaw@gmail.com)

I'm looking forward to using those new connectors on the pots. I've toasted a few of those 3 nub ones.

It might be a while because they are showing no signs of wearing out.

The pots I now provide appear to fit any pedal manufactured now or in the past.

The original pots I began selling (about 20 years ago) had the soldering lugs mounted on the bottom of the pot, not in the conventional format as is the current model that I've been selling for 8 years now. In that previous iteration some Emmons pedal purchasers discovered that the location of the soldering lugs required the frames of the Emmons pedals to be filed down slightly in order for the pots to fit. It must have been an easy task since no one ever returned a pot complaining that they couldn't install it on an Emmons pedal.

The new rectangular Dunlop Hot Potz II potentiometers fit in an Emmons volume pedal better than the original round Dunlop Hot Potz potentiometers did, due to the improved angle of the soldering lugs.

However, the wiring of the new, rectangular Hot Potz II potentiometers is not the same as with the original round Hot Potz potentiometers...

I did not get good, clear instructions for wiring the rectangular Dunlop Hot Potz II potentiometers from the vendor I used and couldn't find them anywhere else, so I made a very easy-to-follow wiring diagram for these potentiometers and posted it at:
