The ELB-1A adds an INSTRUMENT LEVEL effects loop to allow the use of effects devices on either the upper or lower manual of many Hammond organ models. The ELB-1A contains an active buffer circuit which prevents the effects device from loading down the organ signal. Two ELB-1A units can be used to provide an effects loop on each manual.
- Instrument Level effects devices include guitar pedals and other effects devices intended to be placed between an instrument and amplifier.
- Line Level effects devices are typically rack mounted and are designed to accept a higher signal level than instrument level effects devices.
- To use line level effects devices, use the SSP-3A pre-amp and the ELB-3A option.
