I'm thinking about getting an Fdeck Hpf, I just have one question: Will the Fdeck pre improve the sound going from a 1 meg ohm input on my EA Doubler to a 10meg ohm input on the Fdeck. My URB sounds great through the Doubler, but my Ergo EUB is not so great. I use a Realist on the URB and the Ergo has inexpensive piezo contacts under the bridge. I want to eliminate some of the clacky piezo sound from the Ergo and seems it to sound a little distorted at times. Again, the URB is fine. Thanks!
