Default Concentric 500K audio pot with DPDT push/pull?

Hi, I'm wondering if anyone here has any ideas on how to locate a source for stacked dual concentric 500K (or 1M even) audio taper pots with push/pull DPDT switches. They are apparently quite rare and hard to find, but I know they exist, as I own a bass guitar which has one. This is for a similar application where space is extremely limited.

Any ideas? I appreciate any thoughts or pointers to speciality pot distributors....

Heya Bholder!

Have you tried looking at www.digikey.com? or www.mouser.com? These folks have a huge selection of electronics inventory.

Also, you may want to look at the source. If you can find out who made the potentiometer that you already have, you may be able to track down their website and see who distributes their product.

Otherwise, if none of those options work, you can always do some research at www.thomasregister.com.

Good luck bud!

No, I think he wants a dual gang rotary pot, with a push/pull DPDT switch, these have always been very rare devices. Usually you have to obtain them as a spare part from the manufacturer of the item which uses it, in this case a guitar - although, he doesn't appear to actually be needing a replacement, but for something he's building.

I think his best chance is via the guitar spares route, have a look at who sell parts for guitars, or their American source .

There's a lot of bass players about!.

My 13 year old daughter plays bass, she's recording two tracks tonight, one just vocals (a cover of Dido's Thank You) and one vocals and bass, a self penned song written by the 'Girls Music Workshop' she goes to.

She's also rehearsing in a rock band at school, and last week was taken out of an English lesson (as you can imagine, she was heart broken!) to play bass for year 11 GCSE candidates.

She's the only bass player in the school!. There's always work for bass players :lol:

I do mean concentric rotary, not sliders. Thanks for the links and ideas, everyone. I haven't yet disassembled the one bass that has them, but it is from Germany, which of course makes things more interesting yet.

I've been through these links, and just as my previous experience, it seems to be either/or - they have dual concentric, or DPDT plus one pot, but not both. Must be a custom deal for the manufacturer. I'll keep looking!

Melissa reads music (but not bass guitar music!), she plays piano as well (which is where the music reading comes from), plus flute and drums. She's got a piano, a keyboard, a bass guitar, and a flute - she is NOT having a set of drums :lol:

I dropped her off at the studio about 16:30 BST (15:30 GMT), she's going to ring when she wants collecting.

Default Custom modular pots

You're going to have to go after a company such as Bourns or Allen-Bradley for such an animal. As a matter of fact, Tektronix used similar items on some of their equipment. A concentric pot with a push-push or push-pull or momentary-contact switch was not all that unusual, but odd enough that it was an item that was put together by the vendor for a large custom order.

It used to be that you could specify a stacked item like that. Don't mess with the traditional hobby resources, which still includes Digi-Key (they source mostly items from Panasonic for such things), but instead concentrate on the old jobbers such as Newark Electronics or Allied Electronics. Check out their section on pots and zero in on A-B and/or Bourns for what you want. The modular pots they have are about 1" square, so will fit in a fairly small space. Some models are assembled with eyelets and other with screws. I saved all the ones I removed from Tek scopes during repairs when I was with them with the idea that I could assemble my own custom items with the pieces, so it can be done. There's a lot of variance in what you can get with these systems.

Default Finding a 500K audio DPDT pot

Hmmm.... its in a bass guitar... where might I look?

Actually ALLPARTS has them for guitars and basses, as do a lot of guitar part suppliers. I just googled for push-pull dpdt, there they were.

Judging from the date of this post, Im probably too late.
