Inductor help

Hey guys, I need help figuring out which inductor to use on the "Vari-Tones" I'm building (for my guitar projects).
So, my question is...do I actually have to use an inductor that looks like this http://www.mouser.com/ProductDetail/Tri ... zyhrwsQ%3d ...or can I use this type http://www.taydaelectronics.com/inducto ... uctor.html instead :? ? Unfortunately...I don't really know the difference between the two types (sad, but true :oops: ), or which value inductor I need (all I know, is that Torres Engineering, and most other makers use a 1.5 Henry inductor, on their "Varitone" clones). Thanx, in advance for any info/help ahead of time. :mrgreen:

The second one you linked to is 1.5 μH - the μ (sometimes spelled with a 'u') is actually supposed to be a lower-case Greek letter mu. It means "micro" in that context - the inductor is 1.5 microhenries. I'm pretty sure the one you need for a varitone is 1.5 millihenries - or 1,000 times the inductance. Actually, the schematics I've googled show a 1.5 Henry inductor. That would be a million times the value of the one you linked! It's most common for inductors to be rated in millihenries, so a 1.5 Henry inductor may be listed as a 1,500 mH inductor.

'micro' - 1/1,000,000

'milli' - 1/1,000
