Does anyone have any experience with using both a David Gage Realist and another piezo pickup? I know that many people prefer to mix a pickup with a microphone, but I would be concerned about feedback issues with that setup. I really like the warmth and the low-register response of the Realist - the first time I used it I literally had to make sure that the amp was on! However, it really washes out in the higher registers. Solos and higher walking passages just do not have the presence or volume of the other registers. I would love to find a suitable piezo pickup that compliments the Realist's warmth with some more punch and high-register definition. My initial guess is that the Underwood may work - they seem to have a pretty strong character and speak well in the mid-to-upper ranges. Can anyone confirm or dispel this notion? Does anyone have any other suggestions? I am inclined to look to the Raven Labs blender, given the rave reviews I have seen. I know that the Fishman also competes in that space, but I've heard less-than-flattering remarks about that piece and my ProEQ isn't just blowing me away. Again, does anyone have any other ideas? For reference, I play a 1987 Schmidt flatback bass strung with Spirocores, the Realist (duh), the ProEQ, and either an AI Contra or a GK800RB into an Acme Low B2. BTW, I've stuffed the f-holes with foam for better feedback control.
