blown tubing การใช้

From the 12th century, mouth-blown tubes were developed for use in mines.
The width of the resulting doubled-over flat film is equal to half of the blown tube's circumference.
The height of the film line is often 10 times the diameter of the blown tube or more; film lines in excess of 30 meters are possible.
For example, a guitar tech replacing a blown tube with a new one may have to ensure that the tube amplifier still has the same " color " or " warmth " when chords are played through it.
In a " Guitar World " article, lead guitarist Billy Gibbons said that he used a Marshall Major amplifier and a Maestro ring modulator on this song, and that the amplifier had a blown tube during recording which added to the tonal character of the song.
