ESP Guitars Message Board (December 22, 2002) – "THE ESP LTD EC-1000 DELUXE"

"The blamelessly evaluation refers also to the playability of the EC-1000. The extra jumbo frets are well dressed and high polished. Together with the great adjusted bridge and a fine notched nut, it had a string height of 1.2mm (3/64") without any buzzin!!!" (Translation of a Test in a German Guitar Magazine, with translators comment)
"P.S.: I found out, that the EC was likely sent first to a plek-center, before it was sent to the magazine. So that's why the setup was so good in the test. I heard that many distributors do that to get a good test result in playability and so they sell more. I heard now from up to 10 people that the setup of the EC isn't perfect as mentioned in the test." (translators comment)

Harmony Central (July 31, 2001) – "New Fret Dressing Technology at Summer NAMM"

"The international area at Summer NAMM doesn't often draw a lot of attention, but at this year's Nashville NAMM show, a curious piece of machinery called the "plek" caught our attention."
"This oddity was courtesy of a German company that also goes by the name plek, and it was performing a commonly needed task of fret dressing. Aiming to bring high precision to what is otherwise a bit of an art, the plek is a computer controlled machine that carefully measures the fret and fretboard height underneath each string (it actually pushes the string aside slightly so they don't need to be removed, maintaining the tension on the neck)."
