AMS RMX16 Reverb
The AMS RMX16 is a digital reverb used by Prince. Although Prince used it across all instruments, he particularly used it to process drums and the Linn LM-1. He would run the kick drum through the RMX16 on the "Non Lin 2" gated reverb preset to fill out the bass sound, particularly on songs like Kiss that don't feature a bass guitar part. Other examples include the kick drum on "Raspberry Beret" and the snare on "Christoper Tracy's Parade".
