After getting much positive feedback on its playable guitar to honor guitar hero Lester William Polsfuss (Les Paul), Google left its doodle in its United States site for an extra day. In a message on its Twitter account, Google cited "popular demand" in its decision to extend Google Doodle for a day.

In the doodle that came out Thursday, reports GMAnews  hovering the mouse or pointing device over the strings produces a specific note or notes.

Les Paul who died in 2009, notes the Telegraph  was an American guitarist and inventor, best remembered for his work in development of the electric guitar, which made new music styles like rock and roll possible and he is credited popularising innovations such as delay effects, phasing effects and multi-track recording.

Having built one of the world's first solid-body electric guitars in 1940, Paul's design - The Log - was only put into production by manufacturer Gibson in 1946. But in 1961 Gibson, without Paul's knowledge, changed the design to create a lighter and sleeker instument which they named the Gibson Les Paul and immortalised the musician.

While the doodle is accessible only in the US website, users outside the US can get to the digital guitar by by clicking on the "Go to Google.com" link.

The Google site  not only allowed you to try the strings and make the single notes and chords, but ticking the red light you get record and your attempts get recorded and can be played back on the web link shown on the Doodle. Gaberlunzunzie offers his rather weak attempt and urges you to hurry!!   Playback
