Building a volume pedal, need a bit of direction on pot values and such.

I've bought a Elektro Harmonix Micro Pog.

I'm using the Dry Out for my main bass signal.

I feed the Effect Out through a couple of pedals.

Then I blend the two signals back together.

For the time being I'm using a simple DOD "Resistance Mixer" to blend the signals, which sends each signals through a 500K pot + one resistor (value unknown).

I'm halfway building a pedal that blends the signals back together.

The clean main signal is always "on", the on/off switch simply determins if the Effect signal is added or not.

Easy enough to put together, but I want to add a potentio meter to adjust the volume of the effects signal.

Is a 500K pot a good value? I understand passive volume pedals tend to use these. Any other components I'll have to think of, like that resistor?

Thanks!

Sorry, I don't know the answer to your question, and you must have your reasons, but I am a little mystified as to why you would use a volume pedal in what is apparently a studio recording setting. I'd think recording it at a pre-determined level, then pulling it down when you needed/wanted to during re-mix would be far better:
- Recording the instrument(s) at the optimal level;
- No problems caused by rocking too far on or off the volume, and having to re-record or live with it;

IMO, VP's are over-used, anyway- most electric guitars have volume controls on them, already.

It's not for a studio setting, in a studio setting I wouldn't use the Pog, I'd double track.

It's for recreating double tracks live.

Thanks for your enthousiasm though.

'That resistor' is likely there as a mix resistor, so when you turn down the potentiometer, the dry signal isn't grounded out as well. Maybe 220K or 470K at most. Use whatever volume control value that feels right. Try liner as well as audio taper. Try 250K, 500K, or even 1Meg. What do you have to lose; maybe a $2 control if you don't like it?
