Plek-ing a guitar - Yay or nay?

If you have the money then go for it. A plek machine is like an expert luthier making the frets perfect. You will love it.
There are several cool youtube videos showing the process. I know one luthier checked his own results in a Plek machine and they were both in the same ballpark according to the Plek machine data.
I have many guitars and most needed fret jobs due to many years of playing wearing them down and I just couldn't afford fixing the frets on all my guitars so I started learning how to do it myself. Now I have learned the whole process, from creating a new nut to putting new stainless steel frets in and level them to a point where I'm perfectly happy with great playabillity. Is the result 100% like Plek or expert luthier, no, but still very good and they play better than many stock guitars from big brands.

Well, Plek is no magic. If your guitars play fine, I wouldn't get them pleked. If there's need to refret a guitar anyway in the next years or one guitar plays really bad, then Plek is just fine - to me it is as good as a good luthier

A plus with Plek is that the guitar neck and fret data is saved in a convenient way for future events.
This is great for expensive or rare guitars when the owner needs a refret or repair but want it to play identical like before.
It is easy to look at the data and program the Plek machine.
A luthier can do this also but I think it's more convenient with a Plek machine, and any Plek machine around the world can do the same job with the data. Every Luthier is unique.

+1 for a good luthier job.

I have three Gibson guitars, one Les Paul and two Les Paul Juniors, that came from the factory already pleked.
I think their factory setup is superior than on my non- pleked guitars.
That said, I don't feel my other guitars are inferior playing- wise after a decent setup- job (that I mostly do myself).
So in summary if you don't feel your guitars are lacking there's no need for another plek job IMO.

Definitely + 1 for yay IMO.

I have had my 3 guitars plecked and I can clearly see a huge improvement in playability, intonation and sustain, specially on the first positions. They had all been set up by expert luthiers before, but no luthier AFAIK will operate on every single fret optimizing its height and its shape in order to to correct intonation +/-

One drawback is that any oscillation in the neck setting (like variations in temperature or humidity) will reflect over the overall performance tho.

All I know is that my gas is getting the better of me these days, sigh...

Cut down on the curry, Arv.

Oh... you said "gas", but you meant GAS.
