Hi

My BC9 took a nosedive on stage and landed on the pots which made one of them brake of.
now these small 9 series ribbed pots are seemingly impossible to get.
Does anyone know how or where to obtain a spare?

thanks, E

I tried to find one for a similar boss pedal - thought I had it at mouser but I was wrong.  I ended up ordering a replacement from boss/roland.  Ended up costing about 9 or 10 bucks, which was ridiculous, but at least I had a working pedal again.  :-\

Which pot (tone, level, etc.)?.  What value is it?  What size are the stock pots?.

I have the same problem with a tone pot on a modern Boss DS-1, the tone pot is smaller than the others (it's a 9mm, I think the other two are 16mm) and it's a 20K-B pc-mount with a knurled shaft.   Can't find it anywhere except Boss and they are notorious for charging ridiculous prices and shipping.  I found a 16mm, but it's taking a lot of work to make it fit with the other two pots.

How about answering my questions?.  We don't even know what kind of pot you're talking about, except it's a "ribbed" pot, whatever that means.  You haven't said what size or value of pot you are looking for.  We need info.

Sorry about that

Wonderfull pedal the bc9

its a 100 K lin pot. The ibanez 9 series (were the famous ts9 is a part of) use small pots.Their about 1 cm in diameter.
The shaft is aluminium. Which I guess makes it prone to breaking. The shaft is short and has a top end thats ribbed to keep the knobs in place.
A peek of this is visible in this opened up tubescremer. Anyway those are almost imossible to find here.

thanks. E

Now I get it, "ribbed" really means a "knurled" pot.  That "ribbed" term threw me.  I think you need either a 9mm or 13mm 100K-B pot with a 6mm knurled shaft.  If you can actually measure the diameter (in Millimeters) of the pot we could narrow it down.  I've seen pots for Ibanez pedals, so I think it can be found.  Please give that diameter measurement and I think we could help.

I think this is it.

I don't have all the weird values in this style because I have been getting them from Sovtek. That is also why they are more expensive. I'll look into expanding this item next year.

I was thinking he might need the 16mm pots, but he said something about them being about a centimeter in diameter, that's why I asked him to measure them.  The pic looked like 16mm, but I wasn't sure.

I'm also looking for a replacement pot for my BC-9, but it has small board-mounted pots on a daughter board (see pic below).

I'm thinking Mouser has to have something this size that will fit. I guess I'll start looking. :)

But if anybody already knows which part number or brand/type, please let me know. Thanks.

In the mouser catalog I saw an entry for an Alpha 12mm pot.  I bet that would fit it.

Can I find it now?  Can I fu....
Here it is!

This seems pretty close to me.  Shaft is different, but seems like it would work.
Try a little tenderness.

The size would likely be right, but d-shaft is something I'd rather not deal with. There would be no way to get the knobs to match.

I'll keep looking.

Also, the pots you have look like they are the "snap-in" type, in other words they have extra lugs on them that help in securing them to the board.  On some pedals, like the Arion pedals, the extra lugs are actually soldered to the ground of the board, and the case of the pot is a continuation of the ground circuit.
You might want to contact the manufacturer's support, to see if you can get the original replacements.  Sometimes the pots in commercial pedals have been specially made for the manufacturer to their specs, and are hard to find in off-the-shelf replacements.

Fixed it with the larger small bear replacement

I had to change one pot around. But there is one spot that will accept a larger pot.
Had to use the holes from the lugs to attach it so ot would fit.

Well I guess the pictures speak for themselve. Glad it works again :)




Hope this helps with anyone having the same trouble

Rock n roll!

Glad you got it working!.  It does look like the original pots were 12 or 13mm pots, but it seems you were able to get it working with the larger 16mm pot.  Great!.
