building volume pedal

[SirPoonga]

Is a volume pedal just a pot?  I've seen pedal with many options, like a max volume, that's just two pots then, tight?

What about an enclosure?

I thought I remember seeing something like this here before, but search isn't helping.

I spring/wrap a string around a 'flat' potknob/pulley...threading the string through the hole I drill in the pulley so it doesn't slip...one end pulls the pot CCW [spring] the other end attaches to the treadle pedal.
  A pot, wired like your guitar volume or effect volume...or
  If you have room for 9V and a board, put a little Jfet or whatever booster in there and the volume will go from 0 to well above unity...maybe put the booster on a BP switch...
 making the houseing/treadle part that Turns the pot is the tricky part, you need the right spring and room for it..so it pulls the pot all the way CCW, and to align the string/pot/treadle so the string stays on the pulley...I've done a few, worked every time.
 I used a clock spring for one, and fit the whole shebang into a RACO Box. this was a bit tricky...
 The nice thing about 'stringing up' your treadle pots is that any value pot can be used...I have a SS phaser in Vox Treadle with Speed control...

There is a volume cut pedal on the bottom of this page
http://www.vmsrecords.com/dissolute/pedals.html
It has a cap attatched to the volume pot so that highs aren't cut as you decrease, you might want to incorporate that in yours.

Here's one I built, which I have posted in these forums before.

Due to the relatively low impedance, it works best in your effects chain after an effect with an output amp, rather than being connected directly to your guitar.  Mine goes right after my cry-baby, and works fine.

I'm really bad at theory and such (in the way that I know about it) but I was just wondering if this is right, if it's not maybe someone could explain it a little better to me



Thanks

I'd subsitute/eliminate the volume.
 and Put the maximum volume exactly where the volume was.

[robbiemcm]

Yeah but if I wanted a foot pedal that went from a minimum volume level to a max volume level, and the volume was to be a foot volume thing... would mine work on a theoretical basis?

Also not sure what you'd have to make the values or are they a proportionate thing?

As you can see I'm quite useless at circuit theory, I'm just following schematics right now but would like to know how to make my own. Problem is I have no idea how/where I should start learning...

What about an enclosure?

I like this one:



It includes potentiometer and jacks too! :wink:    Let me know if you find something better and cheaper...

PS $69.95USD new. You can often find used the EB 6166 used on ebay for $50.
