This is one of those How-It's-Made factory tour films, which shows how guitar strings are made in the D'Addario factory. It also shows the quality control procedures used to test that the strings are fit for their purpose. The strings are stretched and twisted in a medieval torture chamber until they break. I never knew there was such a thing as a ball-end-sorter.

Servoelectric guitar
Milwaukee Servoelectric Guitar is an ingenious experimental instrument. Individual servos for each string control the string tension, with a clever compensator wheel arrangement. The servos are powered by low cost home made amplifiers. The tension / frequency sensing circuit is a novel design incorporating a potentiometer and springs.
Tube versus solid-state amplifiers
Although solid-state technology dominates modern electronics, vacuum tubes are important in guitar amplifiers representing millions of dollars in annual sales.While solid-state amplifiers create a more faithful reproduction of the signal from the guitar's pickups, players tend to prefer the tone of valve amplifers.
Virtual Acoustic Guitar with Physical Soundboard
A Physical Resonator For A Virtual Guitar is a project from Amit Zoran and Pattie Maes at the MIT Media Laboratory. It is an electro- acoustic guitar with a changeable soundboard. By releasing a catch the middle part of the guitar can be popped out. The strings are secured on a tailpiece, so the soundboard can be changed without taking them off.
The MIDI Pick
You probably don't realise it but when you are playing you hold your pick (or plectrum) in a million different ways. The angle between the pick and the strings, the length of exposed pick and how hard you squeeze the pick all affect the sound you will get. How you hold your pick eventually becomes a sub-conscious thing: difficult to describe but crucial to the sound you get.
Van Halen the Inventor
Ironic Sans has a collection of links to patents filed by celebrities, have a look at Eddie Van Halen's rock-out guitar-support .
Who makes the most guitar models?
There are quite a few guitar models listed in the guitar-list.com database. I thought it would be useful to see how many there are in each category, using the IBM ManyEyes visualization tools. The size of each circle is the number of different models of that brand name. You can click on the links below to explore the diagrams for each type of guitar.
Robert Johnson: finger points to Marfan syndrome?
In September's issue of the British Medical Journal, G.P. David Connell speculates about the unnaturally long fingers of bluesman Robert Johnson . Based on pictures and contemporary accounts, Connell thinks that Johnson had Marfan Syndrome .
Guitar evolution
The modern guitar is the product of thousands of years of evolution. The size, shape and construction of guitars has changed though history, but is this evolution now over?
