2nd question first answered.... I like the neck Nailbomb a lot in that setup - I did a review a bit ago on my FB page ( facebook.com/darthphineas). I have to hunt high and low for neck models that work for my goals and the A-Bomb neck is a good fit for that poplar body, maple neck/board guitar.
have to say, that I've not always had the best luck when trying to describe the voices I'm looking for in a BKP. for example, the Emerald neck and the HD bridge seemed good on paper and are always highly recommended, but they ended up better in different guitars than the ones I wanted them to be in because the tones didn't match up as expected. so....that's why I started by going with how the A-Bombs are what I'm looking for in that poplar body guitar and how I'd like something that would translate similarly for a sapele body. lol! it sorta seems like I'm making 3 left turns to go right, but there's a method at work. ;)
here's an example of my concern...I ran down a list of bands I like to one guy for a suggestion for the poplar strat, one band being Whitesnake. all he hears is Whitesnake and suggested a CS for that same poplar strat. I have a CS in a all mahogany Epi Lester and know it would have not worked at all for what I wanted in that poplar strat.
