The upgrade is a small replacement board for the 3P CPU (IC 44), a board to control chorus speed and a board to add PW wave. It will require removing the CPU and replacing it with a 40pin socket which is supplied with the Upgrade. This needs to be done with good desoldering equipment by a competent technician so that the 3P board is not damaged. Instructions are supplied in the user guide.
