Electric guitars were guitars that used electric signals to create sound.
When Rakweed was going to cover the Earth. Clyde Langer used Haresh Chandra's electric guitar to make the same sounds and vibrations as the school bell of the Park Vale Comprehensive School, which had destroyed the Rakweed before. The guitar sound broke the plants' communication methods and neutralised the Rakweed spores. This killed off the Rakweed and saved Luke Smith's life. (GAME: Sound) Later the electric guitar stood inside Clyde Langer's bed room. (TV: The Curse of Clyde Langer)
The Twelfth Doctor showed himself to be an excellent guitar player. He used his own electric guitar when challenged to an "axe fight" by Bors, although the medieval audience did not understand the play on words. He played "Pretty Woman" when he noticed that Clara Oswald and Missy were watching. (TV: The Magician's Apprentice) He also played the same electric guitar in his TARDIS, this time playing Beethoven's Fifth Symphony, while contemplating the Bootstrap Paradox. (TV: Before the Flood) He was playing "Amazing Grace" on the same guitar when Osgood contacted him about the Zygon uprising. (TV: The Zygon Invasion)
After being separated from his TARDIS and spending some time in Nevada, USA, the Twelfth Doctor acquired a new electric guitar. He wrote a song inspired by his companion, Clara, using this guitar. (TV: Hell Bent) The Doctor later played Beethoven's Fifth Symphony in his office at St Luke's University, before first meeting Bill Potts in person. (TV: The Pilot)
Behind the scenes Edit
