Need help with parapedal pot!!!

Hi
http://cgi.ebay.fr/5pcs-B10K-Dual-Stereo-Potentiometer-Pots-20mm-Shaft-S-/160573140652?pt=Guitar_Accessories&hash=item2562e7aeac

Do you think that pot will be good or shorter?
I saw on banzai effect one pot for the Ibanez WH-10, it looks great but no the good value, is it possible to get 10K with resistors on parralel?

I saw on the board that some guys tried to make this; http://geofex.com/circuits/ldrlfo.htm
But really don't know how it's works

Thanks a lot
