Jonathan Coulton uses a variety of instruments while performing his songs live in concert.
Jonathan's primary instrument is the guitar. He plays guitar for most of his songs, sometimes accompanied by Paul and Storm on backup vocals.
Jonathan purchased a Zendrum MIDI controller in the last half of 2007. He frequently uses it to perform Mr. Fancy Pants in concert, inserting an improvised solo between the song's two verses in order to elongate what is a traditionally short song.
