BTC-1A BASS, TREBLE, PERCUSSION, AND OVERALL LEVEL CONTROLS

This option provides precise control over the organ's bass, treble, percussion and overall level. Mounted on the SSP-3A chassis, these controls allow the organ owner to set sound to his preference and not have to worry about other organists tampering with the settings.

NOTE: The BTC-1A functions only with the SSP-3A.
