Organ
The 1538M08 is part of the M series of Hammond organs produced between 1959 and 1965. It is a two manual, five rank harmonic drawbar tonewheel organ, with keyboards that span two octaves and two preset tabs controlled by drawbars. It has two sets of contact stops, one in the bass and treble sections, each with a 32' tone and a 16' tone. The stops are engaged when the presets are pushed or knobs are moved, allowing for multiple combinations of sounds at once. The 1538M08 also includes a Leslie Speaker, Spring Reverb, and Percussion controls. It has built-in vibrato and chorus effects, as well as vibrato speed and chorus depth controls. The organ also has a built-in tremolo effect.
