Dobro serial number dating
A radiating spider carried the sound from the bridge to the edges of the cone.
Without a block of wood choking it, the inverted resonator vibrated freely and sustained notes longer than the biscuit-bridge cone.
Please note that fender serial numbers tend to overlap by at least a year, and thereby the date of your guitar can only be approximated.
The Dopyeras turned the resonator upside-down and modified its V shape into a W, connected to the bridge by a long screw through the center.National’s president, George Beauchamp, overruled Dopyera and rushed the Triolian into production in late 1928.Beauchamp and Dopyera had been rubbing each other the wrong way for some time, and this came as the last straw.Please be aware that some instruments manufactured in the late '50s cannot be interpreted by this decoder.Our El Cajon, California and Amsterdam, the Netherlands Factory Service Center staff can help with any service, maintenance or repair questions concerning Taylor guitars.
