We love our multiple necked guitars here at guitar-list. This one was made as a custom order for Pat Metheny by Canadian luthier Linda Manzer. Linda Manzer is also responsible for the wedge shaped acoustic: an innovation that makes the guitar more ergonomic.
The Pikasso II has a total of 42 strings. The only problem is by the time you have finished tuning it your audience will have gone home.
Like radioactive giraffes, guitars have been sprouting extra necks for some time now. Witness Jimmy Page's double neck SG on live versions of “Stairway To Heaven” or the guy out of Cheap Trick with his many-necked guitar. Some guitarists have exploited the extra necks to musical effect, like ambidextrous virtuoso Michael Angelo.
