The standard tuning for an electric guitar is E-A-D-G-B-E, with the low E string being the thickest and the high E string being the thinnest. The range of pitch on an electric guitar is from the low E string (82.41 Hz) to the high E string (329.63 Hz).
The range of pitch on an electric guitar can be extended by using different string gauges, different tunings, and different playing techniques. For example, using a heavier string gauge will lower the pitch of the guitar, and using a lighter string gauge will raise the pitch. Using different tunings can also change the range of pitch on the guitar. For example, tuning the guitar to an open G tuning (D-G-D-G-B-D) will lower the overall pitch of the guitar and make it easier to play slide guitar.
Different playing techniques can also be used to extend the range of pitch on an electric guitar. For example, using a whammy bar can bend the pitch of a note up or down, and using a tremolo bar can create a vibrato effect.
