Well then, if you want the sound that said guy is getting, maybe reconsider the Ergo. As has been repeated over and over again in this forum, only a DB sounds like a DB. I have an Ergo and I like it a lot, and I think it is a great buy. But it seems to me that asking string questions for your hypothetical EUB is doing nothing to get you closer to the sound you desire, which by your own admission is an acoustic sound. Why an EUB?
