Hi, I wonder if anyone can help.. I have been trying to find some Dual concentric pots for my project, 10k+10k, with nobs to go with them of course!! Really there is nothing like these babies for parametric E.Q. Once you have used a set up like that, I PROMISE you, everything else SUCKS! Its literally like a curse! I have been trying to find these for YEARS. Thanks :D Peter
