BSL=Basic Scale Length and TSL=Total String Length. TSL effects compensation and BSL effects play-ability.
The Gilbert's have been using a standard scale length BSL of 25.700" plus 0.050" compensation since the early 1980's. Compensation is not part of the scale length but part of the total string length. Gilbert's do not work in millimeters but in decimal inches. 652.78mm is the scale length in mm add 1.27mm for the total string length (which has nothing to do with the scale length play-ability). If you play a 650mm you will notice no difference. A 650 is only 1.39mm shorter than a 652.78. (Remember Nut to XII is 325 for a 650 and Nut to XII is 326.39) Spread over 12 frets the extra length is a 0.12mm from fret to fret wider. That is about the thickness of two sheets of printer paper or two human hairs.
Since about 1986 Bill Gilbert has been building along side his dad and has been signing the labels. They are exactly the same as the ones John built. Especially this one, which is why I chose it. Bill was not allowed to build if he could not equal or surpass his dad's guitars. This one has the feel of the early 1980's Gilbert's that I love.
I have played and examined many Gilbert's and have drawn many plans. This one is the same fan bracing as the ones in the mid to late 1980's. In fact there is a member here who has one that was built for David Russell around 1987(?) and this has the same fan bracing.
Thank you. I attended the Yale Guitar weekend back in the 90's when 'John' was honored by Ben Verdery. All the featured performers used their own John Gilbert in their performances. It was my first exposure to Raphaella Schmitts (sp.?).
I was just curious about the guitar you offer. Thanks for the very thorough explanation.
I have gotten to know Andrea Tacchi and his son Giovanni and see in them the same father son working relationship.
Good luck with the sale.
