años de fabricacion de las pastillas TIM SHAW

[PEDRO72]

Buenas
yo las he visto desde el año 79 hasta el 86 en guitarras mias,
pero alguien sabe exactamente, cual fue el primer año y el ultimo año de fabricacion?
La consulta es porque me he hecho con una Gibson del año 90, una es 175 y por debajo lleva el nº de serie que corresponmde a las tim shaw pero creo que no son las originales poque en el año 90 creo que este modelo ya no se fabricaba

gracias a todos

Las Shaw se fabricaron del 80 al 87. Yo afinaria más y diría desde mediados de 1980. Suelen tener el PatNo troquelado y dos cifras de tres dígitos estampados, el primer grupo se refiere al código interno que Gibson utilizaba para definir sus pastillas y el segundo es el mes y año. No todas las Shaw llevaban este último código estampado.



Me extrañaría mucho ver unas Shaw del 79 y ya no te digo unas del 90.

hola Jose

Yo he visto y tocado una sg de doble mastil con pastillas que llevaban troquelado ese numero, pero no el tampon de tinta y era del 79 igual fueron de las 1as y tengo una es 175 del 90 que tambien llevan las pastillas tim shaw, eso si, la guitarra ha pasado por minimo 3 dueños por lo que supongo que alguno le monto esas pastillas, el ultimo dueño me dijo que eran las originales pero a mi me extraño que en el 90 aun se estuvieran montando esas pastillas , pero la verdad que si lo son , suerte la mia!!!!

al ser una culona no he podido ver si los potes estan soldados varias veces , pero en el proximo cambio de cuerdas desmontare las pastillas y con un espejo intentare hacer unas fotillos

Gracias

Joder, te había puesto un ladrillaco y se ha ido a tomar pol c*lo

En resumen, las Shaw no se incorporaron a producción hasta 1980. Tienen que tener los seis digitos estampados, pero es posible encontrar Shaws de entre el 80 y el 87 sin los seis digitos estampados y también hay pastillas con los digitos estampados que no son Shaws

Lo mejor que puedes hacer para salir de dudas es desmontar la tapa de la pastilla y ver si tiene un T en la bobina, en ese caso es una Ttop, yo sigo pensando en lo mismo, tanto si es del 79 como del 90 no son Shaws.

Copio y pego un artículo del Vintage guitar magazine que cirula por la red:

Whether it was rivalry between plants or increased market awareness, the Nashville plant jumped into the reissue action in 1980. By this time, one of the most glaring deficiencies of new Les Pauls (compared to the originals) was the humbucking pickup. In preparation for its first attempt at a reissue, Gibson assigned engineer Tim Shaw the job of designing a reissue of the original Patent-Applied-For humbucking pickup—within certain restrictions. “This was 1980 and Norlin was already feeling the pinch,” Shaw said, referring to Gibson's long decline through the 1970s and early '80s. “We weren't allowed to do much retooling. We redid the bobbin because it was worn out. We got some old bobbins and put the square hole back in. We did it without the T-hole, which stood for Treble.”

To replicate the magnets, Shaw gathered up magnets from original PAFs and sent them to a lab to be analyzed. “Most were Alnico 2's,” he said, “but some were 5's. In the process of making an Alnico 5, they stick a magnet in a huge coil for orientation, but an unoriented 5 sounds a lot like a 2. They started with Alinco 2 and then switched to Alnico 5.”

Shaw discovered that the original magnets were a little thicker than 1980 production magnets. “Magnetic strength is largely a function of the area of the polarized face; increasing the face size gives you more power,” he explained. So he specified the thicker magnet for the new PAF.

Wiring on the originals was #42 gauge, which Gibson still used. However, the original wire had an enamel coating and the current wire had a polyurethane coat, which also was of a different thickness or “buildup” than that of the original, which affected capacitance. Norlin refused to go the extra mile-or extra buck, as it were. Enamel-coated wire cost a dollar more per pound than polycoated. Shaw could change the spec on the buildup without additional expense, so the thickness of the coating was the same as on the original wire, but he was forced to use the poly coat. The difference is easy to see: purple wire on the originals, orange on the reissues.

Shaw later found a spec for the number of turns on a spec sheet for a 1957 ES-175. “It specified 5,000 turns because a P-90 had 10,000 turns and they cut it in half,” Shaw said. In reality, however, originals had anywhere from 5,000 to 6,000 turns, depending on how tight the coil was wound. Shaw later met Seth Lover, who designed and patented Gibson's humbucker, at a NAMM show. Lover laughed when asked about a spec for windings, and he told Shaw, “We wound them until they were full.”

The spec for resistance was even less exact, Shaw said. The old ohmeter was graduated in increments of .5 (500 ohms). Anywhere between 3.5 and 4 on the meter (3,500 to 4,000 ohms) met the spec. Consequently, Shaw pointed out, there is no such thing as an exact reissue or replica of the 1959 PAF pickup. There can only be a replica of one original PAF, or an average PAF. As Gibson would find out in the early 1990s, the same could be said about the entire guitar.

Shaw's PAF reissue debuted on Gibson's new Nashville-made Les Paul Heritage 80 in 1980. Compared to anything Gibson had previously made (which is to say, compared to nothing), it was an excellent reissue of a sunburst Les Paul Standard. It had a nice top, thin binding in the cutaway, nickel-plated parts, more accurate sunburst finish and smaller headstock, but the body shape, body size and three-piece neck, among other details, were just regular production. It appears that Gibson still didn't understand the demand for an accurate reissue, because Gibson accompanied the Heritage 80 with fancier versions: the Heritage 80 Elite, with an ebony fingerboard that had no relevance to the reissue market (although it did have a one-piece neck) and the Heritage 80 Award, with gold plated hardware that also had no relevance to the reissue market.
