Double Guitar Pan
The double guitar pan consists of two drums, cut to half their lengths, with eight notes in each. The tonal range just above one octave, from D3 to F4. The guitar pan is mostly used as a rhythm instrument, playing chords, in the same way as an ordinary guitar in an orchestra. The common Trinidad layout, called "Invader style", is somewhat peculiar, as it goes from C3 up to F4, but lacks the C#4 and the D#4 in the upper octave. This makes it difficult to do musical arrangements for this instrument.
Overview of Double Guitar pan, Invader style
I have chosen to present an alternative guitar pan designed by tuner Rudy Smith, as this covers a full tonal range from D3 to F4. The layout of the Smith Guitar Pan is designed with notes consequently in drums left-right-left on a chromatic scale in the same way as the double second pan. There are just four octave intervals and the higher notes reside right inside their lower octave counterpart.

Special crafting techniques
While sinking the guitar pan; do not work closer to the rim than 70 mm. This is done to leave material for the outer notes and get the right shape of the sunk basin.
Measures for the Double Guitar pan
