G'day! This is something that has been bugging me for a while, so I'm hoping someone out there can help!! What I'm talking about mainly here are the "9 mm" pots that fit the pedals with the "4-in-a-row" controls, particularly with dual-concentric pots (eg. MT-2, CE-5, etc).
I come across a few pedals with bent/broken pots that are cheap because the parts "arent available". There has to be somewhere on the face of the planet where we can get them? Maybe some of our members located in Asia know of a supplier over there...? There is no one in North America that I can find.
I recently had to ask a friend in Australia to buy and send me some 50k A pots from there (level controls for PW-2 and DS-2). This is a bit nuts...
What I know so far:
1) I'm told Roland USA keep spares for current pedals, but I haven't tried. My expectation is the price will be "high" and the shipping to Canada a pain.
2) There is a one specialty supplier in the USA that carries single-gang pots, but they are set-screw rather than fluted shaft: http://www.smallbearelec.com/Detail.bok?no=693
3) There is a retail supplier in Australia that sells single/dual pots over-the-counter, however, the dual pots are "standard' with the same value on both pots: www.jaycar.com.au (e.g. catalogue number RP8712)
4) There is a manufacturer in California who appears to make the pots we need, but they have not returned my emails enquiring about small quantities: http://www.alphapotentiometers.net/html/pot_selection.html
I would be prepared to buy quantities maybe up to "100 off" if I had to - maybe we could do that... one of us buy a bulk order then distribute them?
Any help is greatly appreciated!! 
These are the pots I'm talking about... (only single gang shown in this pic (it's a PW-2):

Thanks mate!! You rock!!
Expensive little critters aren't they? I'm contemplating contacting one of the pot manufacturers (Alpha) and asking how much a production run of 1000 would be... (just to see) |

Just ordered a bunch of spares from Roland to fix bent/broken pots on my pedals and to have some spares. Easy as 1-2-3. Be here in a week. |

Indeed. $10 for the concentric tone pot was a bit much to choke down, but I only paid $25 for the pedal it's repairing (including shipping) so it's still a good deal.

OK... I've recently received some "current model" pots from Roland (awesome service from Roland Canada by the way).
I ordered some 50k log pots (level pots from an MT-2) hoping to use them to replace the level pot on my PW-2. Cunningly, I ordered some knobs because I knew the new pots were set-screw type, and the existing pot was fluted shaft. Replace the pot and knob, and job's done, or so I thought.
What actually happened is that the flat spot on the pot shaft is 180 degrees around from where it needs to be for the PW-2, so the indicator on the pot goes from "1 o'clock" around to "11 o'clock", instead of from "7 oclock" around to "5 oclock". It works JUST FINE, but the knob doesnt read correctly.
Crap!! Luckily I have some fluted shaft pots on the way from a mate in Australia, so I can wait and it will be OK.
Just thought I'd share this with you in case you are contemplating a similar repair  |

| It's too bad there isn't a cross reference for what pots fit what pedal. |

Bringing this thread back from the dead...
Ive just acquired an SD-2 dual overdrive, but the dual concentric volume pot was sadly damaged in transit. Does anyone happen to know the value of a suitable replacement, or am I probably best contacting Roland UK? |

It should say on the pot. Failing that, you could remove it from the circuit and measure the resistance across the outer pins. If it's a volume pot it's likely to be log rather than linear.
Roland UK are very helpful from my experience with them. I've had some small orders of things like base screws, grommets and switch from them. Some of the parts have to come from japan so take a while, but there are no exorbitant shipping charges. |

According to http://www.taiwanalpha.com/en/contact2.htm, Mouser is the US distributor for Alpha. Maybe Mouser would sell all of Alpha's pots if they were asked?
A couple of years ago I contacted the UK distributor regarding switches. They told me they'll sell me anything from Taiwan Alpha but minimum order was 500 pieces. Mouser sells to end users so their policies are probably different. |

| - Roland Canada is top notch. If you have access to the service notes, the pots are part-numbered there (oop pedals aren't stocked, as noted above) I bet if you catch the parts desk guy on a good day, he'll pull up the service manual on his 'putor and doublecheck the part for you so you hopefully you get a pointer from 7am to 5pm rather than 11am to 9am!
