Goodrich 120 Pot Suggestions

Post by David Dixon »

Any pot suggestions for a goodrich 120? I am going to try and do it myself with the guidance of a veteran player. Any suggestion as to what to buy would be appreciated.

120 Pot

Post by George Macdonald »

I would suggest a Dunlop pot from Tom Bradshaw in California. You can go to his web site under Webb amps in the manufacturers section. George

Lots of people are using the Dunlop Hot Potz that are available from Tom Bradshaw. You shouldn't have any trouble installing it.

The Dunlop is the only one, unless you manage to pry a vintage Allen Bradley out of the wizened claws of an old steel guitarist's closely guarded stash. :whoa: The Dunlop pot has little bumps instead of terminals, but it's workable. FoBro Greg Cutshaw kindly blurped up the whole process, here:

I bought a Dunlop pot from Tom Bradshaw 2 years ago and installed it myself and it's going strong, at least an hour a day, 7 days a week and not one problem.
Greg Cutshaw has instructions on his web site on how to install the pot. Takes a lot of the" how do I" out of the installing.....jr

David...One important note: when removing the original pot, make note of how the string is wound around the pulley, this can save a great deal of frustration later on! If the string is improperly reinstalled, the pedal may work in reverse (up on, down off).

Dunlop pots for sure. You also don't get the losses you get with some other pots. You get a much brighter sound, just like there was no volume pedal between the steel, and the amp. John

Goodrich Pots

Post by Ronnie Vaughn »

I changed out the pot on my Goodrich 120 pedal last month I purchased from Tonetronix it is a lot better than the original,here is the description from their website.

"This is the Goodrich 500K direct replacement pot for the 120, L120, H10K and L10K Series Volume Pedals. After painstaking research and development all Goodrich Volume pedals are now coming equipped with the new ULTRA HIGH LIFE 500K audio taper potentiometer. The High Life Pot is capable of one million cycles, which is almost 10 times the life of the original 500K volume pot. The Goodrich Ultra High Life 500K Potentiometer is suitable for use in any volume pedal that requires the use of a 500K audio taper pot"

This is good news for us who like passive pot pedals. I'll try it.

From the picture on the ToneTronix ToneTronix web site, the PEC (Precision Electronics Corporation) pot they are offering is PEC P/N KA5041S32.

According to this page http://www.precisionelectronics.com/0-40a-010c.html the part number breakdown is:

K = Precision Series, 2W, 1/4" shaft
A = Logarithmic taper
50 = 2 significant digits of resistance
4 = 4 zeros (resistance = 50 x 10000 = 500K)
1 = 10% tolerance
S = slotted shaft
32 = 1" long shaft


According to this page:

http://www.precisionelectronics.com/0-40a-010a.html

the pot is rated for "25,000 cycles" (not millions) and the element is "hot molded carbon", not even close to the quality of the conductive plastic element in the Dunlop Hotpotz.

I have 1 of the old 500K Type J pots. I think this is what was in the pedals back in the 70's.
