Best Pot for Volume Pedal

Matteran · February 10, 2005, 06:03:27 AM

What's the best pot for a volume pedal that will mount onto a cry baby type mount? I'm assuming an Audio Taper, large size. I have the 250k HotPot for a wah, but because i don't have all the parts yet for making my wah, i was just going to make a volume pedal. So, i could use that pot for a reference regarding the size that i need. But what resistance should it be? 100k?

I would use a 1 megohm pot. You might be able to get away with 500K, but you may notice a little loss of your highs. In any case, they should be audio taper pots - a linear pot will seem very abrupt.

Well thats odd. If you noticed my thread on this I have a 500k audio and it is very abrupt. I am going to swap it for a linear and see if that solves my problem. But its odd because I know I saw a LP for sale that said "audio taper pots"...anyways, I am confused beyond belief.

Are you sure it's an audio taper pot? It shouldn't be abrupt with an audio taper pot, but rather, it should work like you would expect a volume control to work - gradually. Maybe you got a mislabled pot or something? :?

Here is the back of the pot.

I hear what you're saying, but that doesn't mean it's really an audio pot. It could conceivably have the wrong guts in it.

Do you have a few verified audio pots lyin' around? You could do some A/B tests with it. Also, if it were really a linear pot and if you were to measure the resistance at midway, you should measure 50% when the knob is at the mid point. If it's not 50%, then it's an audio pot and it could just be due to the mechanics of the CryBaby shell - it may just turn the pot too fast compared to say an Ernie Ball volume pedal. There is quite a bit of difference in the amount of travel between the two. The more I think about it, the more likely that is your real problem IMO.

Well, mine isn't in a crybaby shell. Mine is just sitting by itself in the open. I haven't even soldered anything yet. When I do its going into a box with a knob for control.

I am posting the rest of my problem in my thread.

Oh sorry, got you confused with the original poster. :oops:

I hope you get it figured out, because something sounds kinda strange. I built a "volume box" myself. It's on my pedal board serving as an attenuator...
