The EPI-7 expression pedal interface allows the popular Yamaha FC-7 volume pedal to function as an expression pedal with SSP-3 and SSP-3A pre-amps in applications where the organ has been made portable and the original mechanical swell linkage is not used.
As built, Trek II SSP-3 and SSP-3A pre-amps have the ability to operate only with pedals employing a 100K pot. The EPI-7 overcomes this limitation and allows pedals with other resistance values like the FC-7 to function properly.
Simple plug-in hook-up in new or existing installations.
NOTE REGARDING PORTABILIZED OR CHOPPED HAMMOND ORGANS:
By definition, SSP-3A installations in portabilized or chopped Hammond organs are non-standard. Many factors including pre-amp configuration, reverb tank mounting orientation, reverb control style, and swell method will depend on the organ components used and the portable cabinet design selected. In order to insure that the component configuration we supply best matches the requirements of your special application, we strongly recommend that you contact one of our customer service representatives BEFORE placing your order.
