Custom shop texas specials are available in every corner store. swapping them back in to make it original again is a 10 minute job... but then i guess his pricing should reflect that... my time cost alone is $1200 per hour..
I guess his price should reflect the fact he has 'faffed' around with it in the first place especially as the body paint does chip very easily etc.......
As far as I'm concerned, stock MK Strat is not the "holy grail" in terms of wiring, etc., it's just a Strat from 2000s Fender.
A friend of mine got the MK Strat and rewired pretty much everything, with better wires, insulation, etc.
Originality matters, but I don't think it's on that level of preserving it like a museum piece.
After all, we also know that MK's actual instruments are hand build by Fender Custom Shop luthier Todd Krause. It's not like he just went to the guitar store and bought them! Just my 5 cents.
Anyway, even if MK's actual instruments are not hand built by Fender Custom shop guys, it's been in service by a guitar tech with decades of experience and I bet he also did some work on these.
