Awesome.....you said....
"I've also had an all hog (Martin 000-15sm) and have the hog/cedar 514ce now. I went to both of them from a GS8 (IR/Sitka), which I loved, but something happened to me along the way where sitka became too bright and rosewood's overtones became too much. I really enjoy the clarity of mahogany, but I wanted bass as well."
BINGO!!!!! my thoughts exactly..... Man, I love conversations like this.....again, it's why I love UTGF.....I can't play all of these guitars but I can talk to those who have, and for those who are kind enough to continue to answer....God Bless you all! love your "something happened to me along the way" line.....my beautiful 2013 514e FLTD (not quite the bottom or headroom and what you said about bright) my beautiful 2012 810e Proto (almost perfect, and what you said about overtones)...sometimes they actually get in the way .... last week I remembered what ntotoro suggested last summer....."Doug, if you want what you describe as a "bigger" version of your 514FLTD, maybe try the 516 version"...well I never found one, never tried one, until ntotoro helped me find one last week....it's now mine and I can't put it down...there's the formula, awesome, european spruce, figured mahogany, CV Adi bracing, etc....yup, something happened to me along the way too...while living with bright and midrange and overtones and bass, and while trying to decide which do I sell (514 FLTD, 520 FE, 810 Proto or the 818 FE) I find a guitar that is a little bit of all four of my favorites! Jersey and Awesome, what you suggested I find......I believe I have! Thanks, Nick!
