1、SERIALIZATION, cont.1183 SERIALIZATION POTENTIOMETER CODING: SOURCE DATE CODE An important instrument dating breakthrough developed by Hans Moust (author, The Guild Guitar Book) is that stamped on every potentiometer (volume and tone pots) is a six- or seven-digit source code that tells who made the

2、 pot, as well as the week and the year. The source dating code is an element of standardization that is administered by the Electronics Industries Association (EIA), formed in 1924. The EIA assigns each manufacturer a three-digit code (there are some with one, two or four digits). Mousts research ha

3、s indicatedthat there are no source date codes on any guitar pots before the late 1940s, and no single-digit year code after 1959 (six-digit source code). Its fairly easy to crack the source code. The first three digits indicate the com pany that built the potentiometer. Sometimes these digits may b

4、e separated by a space, a hyphen, or a period. The most common company codes are: 137 CTS 304 Stackpole 140 Clarostat 134 Centralab 106 Allen Bradley 381 Bourns Networks If the code is only six digits long, then the fourth digit is the year code (between 1947 and 1959). If the code is seven digits l

5、ong, then the fourth and fifth digits indicate the year. The final two digits in either of the codes indicate the week of the year the potentiometer was built. Any final two digits with a code number over 52 possibly indicate a part number instead of a week of the year code. When dating an instrumen

6、t by the pot code, keep two things in mind: The potentiometers must be original to the piece (new solder, or a date code that is off by ten or more years is a good giveaway to spot replacement pots); and the pot code only indicates when the potentiometer was built! If the pot is an orig inal, it ind

7、icates a date before which the guitar could not have been built so its always a good idea to have extra reference material around. Mousts research has indicated that virtually all Fenders from 1966 to 1969 have pots dated from 1966. Moust has speculated that when CBS bought Fender, they found a good

8、 deal on pots and bought a three- year supply. Guild apparently had the same good fortune in 1979, for when Moust visited the factory they still had a good supply of 79 pots - which explains why every Guild since then has had similarly dated pots! Finally, a word of caution: not all potentiometer ma

9、nufacturers subscribed to the EIA source code date, and early Japanese components did not use the international coding like the American and European builders. If the code does not fit the above criteria, dont force it and skew your dating results. (Source: George Gruhn and Walter Carter, Guitar Pla

10、yer Magazine, October 1990) ALEMBIC Every instrument the company has produced has a corresponding instrument file which contains the original work order (specifications), returned warranty, and any other relevant paperwork. In general, the first two numbers in the serial number are the year the inst

11、ru ment was completed and the letter code designates the model. The final two to five digits indicate the individual instrument and its place in the overall Ale mbic production. Alembic started with the number 1 in 1972, and has pro gressed sequentially ever since. An “A” or “B” after the serial num

12、ber indicates the rare occasion when a serial number has been duplicated. On new instruments, the serial number is stamped on the truss rod cover and also in the electronics cavity (Epic and Orion models have the number stamped on the back of the peghead and in the electronics cavity). On older inst

13、ruments, the serial number is stamped directly on the ebony fingerboard below the 24th fret. The earliest Alembic models have serial numbers stamped on top of the headstock. ARIA/ARIA PRO II Aria started using serial numbers in the mid-1970s, and models before this have no serial number. Several dif

14、ferent schemes have been used for serializa tion. Guitars built between 1979 and 1987 may use either one of these for mats: YNNNNN or YYNNNNNN. The first one or two digits indicate the year. A 79XXXXX would be a 1979 and a 2XXXXXX would be a 1982. Some models built in Korea may use a year and week c

15、ode for the first four digits. Serial numbers after 1987 are unknown at this point. Keep in mind that sev eral variations have been used and anything is quite possible.

16、 the B.C. Rich trademark was adopted, Rico built acoustic guitars for the first two years, and then switched to custom- built solid body electrics. When production formally commenced in 1972, the first 350 guitars were numbered sequentially. In 1974, a serial number code was devised. The five-digit

17、serial number was encoded YYZZZ, with the first two digits indicating the year and the last three indicating consecutive production. By the late 1970s, they ran out of numbers and had to begin using serial numbers meant for the following years produc tion. In 1980, the year digits were two years ahe

18、ad, and by 1981, they were off by four years! Currently, the American-made B.C. Rich serialization does provide numbers which correspond to the year, as well as the quantity of guitars that were built in that year. For example: 953001995 (300th instrument produced) 960021996 (2nd instrument produced

19、) The serialization on the Import series models is for identification only, and does not depict the year of manufacture. B.C. Rich does maintain records that indicate the year of manufacture (and the manufacturer) if they are needed. (Source: Bernie Rich, President/Founder of B.C. Rich International

21、ody electric guitars and basses, and one cello. The 11 semi-hollow electrics include six unique, carved top, semi- hollow electrics made between 1982 and 1986. The other five include three prototypes for, and two finished examples of, his new “benny” semi-hollow electric line introduced in 1998. The

22、 209 electric solid bodies include 157 electric guitars and 52 electric basses. Benedetto began making them in 1986 with John Buscarino. He stopped making them in the Spring of 1987. The 11 semi-hollow electrics and the one classical guitar are included in the archtop guitar serial numbering sys- te

23、m. The two mandolins have no serial numbers. The violins, violas, and cello have their own serial number system (starting with #101) as do the electric solid body guitars and basses (starting with #1001). Serial Numbers: All Benedetto archtop guitars (except his first two) are numbered in one series

24、, electric solidbodies and basses each have their own separate series, as do the violins, violas and cello. Archtop guitars have a four- or five- digit serial num ber with configuration #(#)YY. two (or three) digits #(#) indicate ranking, beginning with #1 in 1968. The last two digits (YY) indicate

25、the year. Example: 43599 was made in 1999 and is the 435th archtop made since 1968.

30、lding L. C. Kiesel Company, Carvin has expanded through the years into a full line mail order company that offers guitars, basses, amplifiers, P.A. gear, and replacement parts. The company initially offered kit-built guitars, and, by 1964, completed models. The 2,000 to 4,000 instruments built betwe

31、en 1964 and 1970 did not have serial numbers. The first serial number issued in 1970 was number 5000, and numbers since then have been sequential. Serial numbers up until the late 1990s were stamped on the jackplate. On models with rounded edges and no jackplates, the serial number was stamped into

32、the end of the fingerboard unless it was maple. In that case, the number may be stamped inside the con trol cavity cover plate. Carvins serialization is sequential, but there appears to be no logical order in the way they are assigned. A TL60 built in 2002 has a serial number of 63663 while a Bolt b

33、uilt in 2000 has a serial number of 82398, and an LB70 bass built in 1998 has a serial number of 63094. The following chart of serial num bers contains several overlaps in numbers.

In order to cor rectly identify the year of your guitar, check the neckplate, body, and neck with the correct logo. The seria

36、l number is stamped onto the raised letter neckplate and runs to 5491. Plates with the number 5492 are considered non-authentic because several of these plates escaped the factory and were easy to forge. Five-digit serial numbers also appear occasionally.

38、ions or nuances of the customer commissioning the instrument. In the course of his brief lifetime, he created 1,164 numbered guitars, as well as unnumbered mandolins, novelty instruments, and the necks for the plywood semi-hollowbody electrics. The objective of this list is to help identify the prod

39、uction of numbered guitars. DAngelico kept a pair of ledger books and some loose sheets of paper as a log of the guitars created, models, date of completion (or possibly the date of ship meng), the person or business to whom the guitar was sold, and the date. The following list is a rough approximat

43、us serial numbers were generally placed on the back of the peghead or on a label inside the body. The main body of the serial number is followed by an additional pair of digits and a letter. This additional pair of numbers indicate the production year. For example: 51334 63L 1963 65939 70L 1970 Sour

44、ce: Tony Bacon and Barry Moorehouse, The Bass Book, GPI Books, 1995. GIBSON Identifying Gibson instruments by serial number is tricky at best, and down right impossible in some cases. The best method of identifying them is to use a combination of the serial number, the factory order number and any f

45、eatures that are particular to a specific time. (i.e. logo design change, headstock volutes, etc). In addition to the above serial number information, Gibson also used Fac tory Order Numbers (F O N) to track batches of instruments being pro duced at the time. In the earlier years at Gibson, guitars

46、were normally built in batches of forty instruments. Gibsons Factory Order Numbers were an internal coding that followed the group of instruments through the factory. Thus, the older Gibson guitars may have a serial number and a F O N. The F O N may indicate the year, batch number, and the ranking (

47、order of production within the batch of forty). This system is useful in helping to date and authenticate instruments. There are three separate groupings of numbers that have been identified and which are used for their accuracy. The numbers are usually stamped or written on the instruments back and

48、 seen through the lower f-hole or round soundhole, or maybe impressed on the back of the headstock. Code Letter F O Ns were discontinued after 1941, and any instruments made during or right after World War II do not bear an F O N codes. In 1949, a four digit F O N was used, but not in conjunction wi

49、th any code letter indi cating the year. From 1952-1961, the F O N scheme followed the pattern of a letter, the batch number, and an instrument ranking number (when the guitar was built in the run of forty). The F O N is the only identification number on Gibsons lower grade models (like the ES-125, ES-140, J-160E, etc.) which do not feature a paper label. Higher grade models (such as the Super 400, L-5, J-200, etc.) fea ture both a serial number and a FON. When both numbers are present on a higher grade model, remember that the FON was assigned at the beginning of the production run, w
