the sizes of the neck at the nut 42mm and 56mm at the body fret.
as to the Pickups supplied, besides the H-S-H configuration i'm not too sure what type of pickups they are..and am sure will be upgraded in time, maybe something like Irongear pickups.. but that said, my other blackbeard kit The SG, I'm for now very happy with the Pickups.
I'm looking to add more strings to the Strat out the Box Softer Springs will flex or give under vibration, robbing the string of energy.. I want more sustain and stability out of the strings and was abit shocked at the pricing i saw for 3 springs.. R350 off RARU for something I know i could have made up for between R5 and R20 each..but would need to take quantities..
As to the tremolo block from the bit of research I have done, if you can stay away from brass.. its of a much lower density, not as solid and absorbs more energy, Robbing you of Sustain, rather go for Stainless Steel
