Ghost by Graph Tech Model # 0780-00 Acousti-Phonic & Hexpander Bass Kit (complete)

Fantastic versatility, outstanding natural tone a midi possibility

I have been using GHOST acoustic phonic and midi expander for a decade on my basses and this is by far the best upgrade you can do on a bass. The acoustic tone is outstanding, the midi out is as good if not better than the Roland , and everything is integrated so it is really simple to use. With one switch you can move from an acoustic double bass tone to an electric bass and to a midi synth. I love it ! I suspect the quality of the component has improved, as I find the bass preamp better than the earlier models I had.
