Ill keep this short, sweet, and to the point
1) found a sick peice of poplar... but I've never heard of poplar being used for a fret board. Its a hardwood, resists warping pretty well, but is it unsuitable for a fretboard for any reason? Googling doesnt provide much help here. Theres no green color ,its all black, purple, and white/brown.

2) goin with poplar top, mahogany body. Pretty cut and dry. Tones should balance nicely no?
3) titebond 2... I used titebond 3 last time, and I thought you guys were gonna kill me... but that was months ago, my guitar has been sitting in a VERY humid garage, and theres no warping, or movement at all. Glue is cheap enough, but I havent really found a good answer as to why 2 over 3 other then "just because".... If someone can take the time to explain this to me, Id appreciate it. NOT using hide glue, not my cup of tea lol.
4) for grain filler, Im lookin at epoxy. Ive used deft in the past as well, but nothing with as open grain as oak has. Thoughts?
