Photon-ajuitar

Despite the name being similar to "guitar," and thus implying a stringed instrument, the ajuitar has a keyboard. Maybe it has both?

If Arthur Dent had been within five miles of the speaker silos then his expiring thought would have been that in both size and shape the sound rig closely resembled Manhattan. Risen out of the silos, the neutron-phase speaker stacks towered monstrously against the sky, obscuring the banks of plutonium reactors and seismic amps behind them. Buried deep in the city of speakers lay the instruments that the musicians would control from their ship, the massive photon-ajuitar, the bass detonator and the Megabang drum complex.
