Noob question - pot values

[Willybomb]

Sorry guys, I've had a search around the forums and had a browse of the FAQs but I can't seem to find it.  Maybe too many trees to see the forest, or maybe it's a just a male thing and I can't see the thing right in front of me.

Anyway, what value pots are generally used for pedals?  250k?  500k? 1meg?  Audio taper?  Does it matter to anything except the control response?

Look at some different schematics and see how much variation you can spot!

Log taper is the best choice for volume controls, so that you see a smooth increase across the range.

Actual values will be chosen depending on how they are being used - could be affecting gain, filter frequency, transistor bias, a multitude of things.

Is your question intended to identify a range of values and tapers to order so that you can be "prepared"?

The full range from 1K to 1meg & most commonly linear & audio taper

Does it matter to anything except the control response?

only the sweep will be different...you can many times just get away with linear.

Well, yeah.  I'm going to make a few pedals shortly (Little Angel, Krankosaurus et al) and I was trying to determine a general rule of thumb.  A closer check of the schematics and BOM usually works for specifics.

There's a joke in there somewhere, right?

Yep. But it is high on bandwidth and low on gain.

(Sorry, but I could not think of anything really clever to say)

If you are looking to create a stockpile, buy the minimum quantity to get a price break - funds permitting of course. This can save money over the long run if you intend to build many pedals. That last part is important. If you only have intrest in a few effects or will be building just a few every year, you may be better off buying what the project calls for as needed.

1k, 2k, 5k, 10k, 20k, 50k, 100k, 250k, 500k, 1m
that's $5  ...and 2k, 20k and 1m are less common

Also price check smallbear. Last I bought, he combines multiple values to meet the discount level.
