after permanently switching from bass to keyboards, tandy's initial onstage setup was of minimoog synthesizer and wurlitzer electric piano and occasionally grand piano (as seen on elo's performance of "roll over beethoven" on "the midnight special"), which he otherwise used mainly in the studio. however, he gradually added more keyboards to his stage and studio rig, notably the hohner clavinet, mellotron (which was largely relegated to stage use), and other synthesizers, and he began to make more regular use of the grand piano both on stage and in the studio. he also used the yamaha cs80, arp 2600, arp omni, polymoog, micromoog, arp quadra, and oberheim synthesizers from the late 1970s to the early 1980s. tandy played a harmonium on "kuiama" on "elo 2".
