I've been asked a lot about this machine. Having been at the bench for dealers of Martin, Collings, Taylor, Suhr, Gibson Custom and other manufacturers using Plek, I have seen the worst and best of what this machine has to offer, fresh from the manufacturer. In the best cases, it is extremely good however, there was not a single guitar that left the store that still wasn't in need of fine tuning.
I think, for manufacture or an extremely busy shop, it could be an asset.
But I think the best way of considering this machine is considering what has been accomplished by musicians on guitar (fretted instrument) to this day. I could write two lists to answer the question of the need for a Plek'd instrument. One list would contain the name of every virtuoso of the guitar to date that has accomplished their amazing feats using a Plek'd guitar. The other list would contain the names of every guitar virtuoso that didn't use a Plek'd guitar to accomplish their amazing feats. One list would be extremely long and the other might very possibly not contain even a single name. Anyone care to guess which list is which?
