Long Necked Pots |
|
|
Hey all,
Do any of you know where I can find some long-necked 100k pots, suitable for use inside a Gibson Les Paul? These are ordinary pots, except the threaded bushings are extra long to permit their pushing through the cavity of a guitar. I know where to find 1M and 500k types, for passive electronics, but I want to design and build an active circuit for my git-fiddle and need 100K. I could probably make 10k work as well, if that's easier to find.
And I suppose I'm really pushing it here, but have you ever seen any long-necked dual 100K? (I'd like to make an active pickup blend control, too).
Any ideas?

Hi Thomas,
I have run across these (check the 100K audio "mini")
http://www.guitarpartsresource.com/electrical_minipots.htm
Unfortunately, no dual. They DO have a nifty 250K dual concentric for about $12 (fairly reasonable in the land of dual concentric pots).
And these guys have some that LOOK like they might fill the bill (see pg 3), but it might take a call to get the exact length of the bushing.

Also, if a 3/8" threaded bushing is long enough (probably not), Mouser does have a dual Alpha 100K in a 12mm body.

Synchronicity strikes again. I didn't pay much attention to what they looked like, but as I pawed through my brand new Mouser catalog last night, I noticed they had Bourns Guitar Pots. Don't know if that's terribly new for them, but it surprised the hell out of me. I'll see if I can find them on their web site. _________________ My Site Last edited by Scott Stites on Thu Aug 16, 2007 6:42 am; edited 1 time in total |

Found this:
http://www.mouser.com/catalog/631/580.pdf
This gives a good pic of them. 250K and 500K in two different styles. This doesn't look like the page I recall seeing - I'll check the catalog again tonight. Can't go wrong with Bourns, though. That's the brand of multi-turn I had on my sad little keyboard, if you remember, Thomas _________________ My Site |

Thanks for the leads, guys.
I probably should have been more clear about values. I'm aware of the 250K on-up long-necked pots. Stewart-McDonald has them. These are great for passive guitar electronics, and in fact what I'm using right now. (Big values are needed since the pickups have a fairly high output impedance).
However for best noise performance in my proposed active electronics (the pickups are buffered now), I should probably use 100K on-down. In fact, the filter will probably need 10K.
Most Gibson guitars need 3/4" threaded bushings to get through the wood.
That's a tall order: 3/4" bushing in 10k or 100k values! I wonder if they even exist?

Hey Studs,
I wonder if these would work - the neck seems to be as long as the guitar pots, but the values are more in line with what you're looking for (1K, 5K, 10K and 50K in audio and linear taper). They're available in cermet or conductive plastic (CP would have a longer rotational life). I'm not sure if the shaft size would accomodate the project?

Cheerios,

And they can handle 30G of shock, which I think is more than the average whiskey bottle can deliver..... _________________ My Site |
