Hi

I am going to build the Deep Blue Delay for my next project and would like to add an expression pedal jack to control the MIX remotely.

According to the information here: http://www.geofex.com/Article_Folders/xprnped.htm the mod itself should be relatively simple. But as for the expression pedal I would like to use my Ernie Ball VpJr with a TRS Cable like shown here: http://www.strymon.net/2011/10/10/strymon-tech-corner-3-volume-pedal-as-an-expression-pedal/

The article on adding an expression pedal jack states that I need to use a pot for the expression that matches the one in the effect - in this case a 50k lin. The pot in my VPJr is 250k log. I know that the taper is going to be different when using an audio pot, but how much will the added value matter?

Alternatively i have a broken Crybaby lying around that can be rebuilt.
