East DJ-RETRO 01 Manual

The DJ-RETRO 01 is designed to fit directly into the Lakland Daryl Jones Signature bass without
modification, including a PP3 battery. Its high quality circuit uses three stacked knobs and includes
an active blend circuit plus a 3 band equaliser with bass, variable frequency mid, treble and bright
function. The active blend circuit prevents the loss associated with many passive basses where,
when both pickups are up full, the signal from one pickup feeds into the other and vice versa.
However, a switch is included to allow a passive equal mix of both pickups. A second switch - basic
"get-you-out-of-trouble" passive mode is included in case the battery dies in crucial circumstances,
and thismodeallows useable settings too.
VOLUME & BLEND
!
VOLUME
!
The upper knob is the Volume. This knob has active circuitry after it so that the feed to your amplifier is a
low impedance drive.
BLEND & PICKUPS SWITCH
!
The lower outer knob is the Blend balance for the pickups. Turn it fully clockwise for the neck pickup alone
and fully anti-clockwise for the bridge pickup. The midway position, which has an indent, gives an equal
mix of both pickups. The balance between the pickups is continuously variable with progressive level
compensation towards the single pickup settings.
