: Maybe you need a buffering unit between the piezo and amp to get a proper impedance match. I don't know what is the input impedance of the GK though.
: A small preamp such as the K&K, Fishman, etc. should suffice.
: See if you can try a buffering preamp as a test.
: Another thing I'm thinking of is the finish of the Velvets.
: Is it round wire?
: This would generate a noise that the pickup will sadly catch very much.
: Hope this helps.
If it is the Velvet 360's, then it probably is the winding. Last year I switched to 180's, which is supposedly the orchestral version and liked them much better than the 360's for pizz, due to the smoother round wire. The ringing overtones I would get on the low E string were always magnified, and I seem to remember at the time I was using the same pickup /mic combonation through an AI Contra and having similar problems. They went away when I switched strings. With an eq you cna probably diminish that frequency. I changed strings before I started using the Schertler Dyn-B, so I have no idea how if the pickup made things worse or not.
