"I am often asked my opinion of the PLEK machine.....
I was one of the first people that PLEK approached many years ago....and I have stayed current on the improvements they have made over time. Honestly, I have yet to find a good reason to purchase a PLEK.
First of all, I made my reputation on my fretwork. There is no machine on the planet that can do better fretwork than Sadowsky Guitars. Second, there is a fundamental flaw with the logic behind the PLEK. 99% of all neck problems are in the true-ness of the fingerboard. I am fundamentally opposed to removing material from the frets to compensate for problems in the fingerboard. If there is a playability issue with one of my instruments, I will remove the frets, rework the fingerboard and then refret with our impeccable fretwork.
I can see some benefit to companies that import a lot of inexpensive instruments or to repair shops that do a lot of fret dressing and set-up work. However, a PLEK machine brings no "value added" to Sadowsky Guitars, other than having to pass the $100,000 + expense to my customers.
My final word on the subject is that the US sales representative for PLEK, after working on one of my instruments, called to tell me "Roger--you are about the only builder I know who does not need a PLEK"."
