Inductor help

Ok, you got your soldering iron and nothing is going to hold you back, but you have no clue where to start or what to build. There were others before you with the same questions... read them first.

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
