Brent Mason is also a human being and human beings are pattern recognition animals. Red berries kill member of group, red berries must be bad. Caves bad cause sabertooth tigers may be in them. Pattern recognition was what kept us alive. It also causes us to think that there are patterns when there aren't. That is why we have conspiracy theories. And some would argue religions. And the same applies to guitars and guitar players. Hmm, strings of brand X break less, therefore they must be better. Picks of brand Y play better, therefore they must be better. And sometimes our system sees patterns where there aren't. Like tonewood. Brent Mason is human like the rest of us so he too may think something works for him that the rest of us might think are bonkers. It might work, it might be his pattern recognition causing him to think it is.
And even if it weren't the case, what works for Brent Mason doesn't have to work for you. Some people love fat necks, others hate them.
I had two identical Strats, exact same model and series. One played good, the other played great. So I agree, just like electronic components have tolerances so two identical pedals of the same production run can sound different, the same applies to guitars. Which is why you shouldn't order guitars online but try them out in person.
