Default High inductance inductors

Hey there everyone,
I decided to join up here since my frustration at the lack of information of this topic on the web is growing at a rapid rate.

I need a 1.5 henry inductor (I know it sounds massive, but it's right for what I want to do) and I can not find a single place on the net that even makes them, let alone sells them. It's for a low voltage circuit, basically I want to convert the tone pot of my guitar to a mid-range, and need one to go from the left tab to ground.

Anyone have any idea who I could get a small number (no more than five) from?
Thanks,
Daniel

What kind of current does it need to handle? Chokes up to and past 100 henries are common in tube amps.
I'm guessing small signal, that might be a little harder to find these days. Might be able to find a 10mA or so choke though.

Would this be what you're looking for:

Hammond Chokes

Dantwomey-
Right amount of inductance, but the current handling is too high.
I think the maximum output of my pickups is less than a volt; so I guess the current handling would be *line level*.

Default inductor

Dont know... but it seems to me that you are looking for somthing like : http://www.geofex.com/

search for the wahwha...The Technology of Wah Pedals
Version 1.7 9/27/99

Ive used some different "transformator" (use just one side of the transformator) to get what I searched for.
hope this helps

Default if its for a low current ap

you can use a high permeability torroid and wind it yourself

To wind a "torroid " as jackinnj suggested I thik would be hard, maybe he ment a ferritcore. Look it up in any eletronic supply cataloguge and see how many windings you need, but I think it would be something like 700 (or in that region)
What you need is 2 halfs of core and a boobin and copperwire (insulatet) and a small handdriven drill. The diameter of the Cu-wire depends how much losses you can accept (you'll wind up with a wireresistor ) But for your purpose take the cheepest ( somthing like a #35 or 0,1mm....
If you dont find any give me a mail I I see what I can do.

That'd work fine (no hum pickup either) but I think it would be a job only suitable for visitors to purgatory I wound up a 1.2 Henry inductor on an ETD34 core a few weeks ago and it needed about 800 turns IIRC. It has a bobbin though so that makes it really easy. That's my choice.

Ah, gammelmalle. I didn't refresh the page before I posted so I didn't see your post.
