1 Windsordave 1 year ago While this survey will be of interest to fellow owners of the iconic Gretsch Super Chet, it will add to our knowledge of these guitars in general. The reason I decided to conduct a survey is due to Gretsch changing the necks from the wider 1.75" width they initially came with, along with a 24.6" scale, to the standard Gretsch width of 1.685" and to-be-determined scale length.I first contacted Taffy to get the dimensions - neck width and depth at various locations on the neck as his guitar is one of the very earliest - Dec '71 - one of only 6-7 made with the bookend tip of the headstock and gold faced Filtertron pups. Mine is from June '72 and as far as I've seen, IIRC, the switch in necks occurred in late '73; however several years back when I was looking for one, I did run across one guitar with the narrowed neck whose S/N was earlier - maybe a '74 - than another example I inquired about still with the wider neck. As most of you know, I had the neck of my SC sanded down to match the profile of my Gibson Country Gent, which not only reduced the thickness but simultaneously removed the D-shaped 'shoulders' making the new profile a shallow C. Unfortunately it didn't occur to me to measure the neck before giving it to Nicole for all the work I had done, to compare the before and after thicknesses which is the other thing I'll be able to learn from this survey. Paul didn't use calipers as I did to measure the thicknesses along the neck but using a tape he did some estimates for me and said his appeared to be approx. .875" at the nut, and 1" at the 5th and 12th which makes sense, the bottom of the neck being flat on the early versions....a very pronounced D-shape.Okay.....here's how I took the measurements. I slacked off the strings and took the measurements directly behind the frets, not on top of the fret as we all have different size frets. I used a digital caliper for accuracy and here's what I found for the 'new' profile on my SC. I've put everything in Imperial numbers vs metric so it'll be easier for comparisons. If you'd please do the same it would be appreciated. [behind] 1st fret: width - 1.84".......thickness - .80" 5th " 1.98" " .80" 12th " 2.17" " .92" 14th " 2.26" " 1.04"It would be nice if we could get several examples of both the original dimension necks and those after the change to the standard neck. We might even be able to somewhat pin down when the changeover occurred. Thanks folks!
