The U-RETRO 01, based on the J-RETRO 01 is a universal highly flexible
on-board dual input preamp and EQ system. The standard pots have 10.0mm
threaded bushes to allow rear mounting in the wood of a bass body, or
6.0mm bushes, for plate or scratch plate mounting, can be supplied to
special order. Flat wire connections to the pots and toggle switches allow
for flexible layout.
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 as this
can give a subtle difference in sound. A second switch allows some basic
passive modes with lots of useful settings too.
Each pickup input has its own individual input amplifier, each with a
gain trim adjustment preset. This means that pickups of different types
and output levels can be readily matched without compromise.
HARDWARE: Chrome, Black or Gold finish.
PASSIVE TONE OPTION: An additional Passive Tone pot can be supplied wired,
which functions in both active and passive modes.
POWER REQUIREMENTS: 9-18V, 2.5mA
The U-RETRO 01 5 KNOB DELUXE bass pre, based on the J-RETRO 01, is a
universal highly flexible on-board preamp and 3 band EQ system. Its high
quality circuit uses three single knobs and two dual concentric knob stacks.
Unlike the J-Retro, its blend is passive in order that the blend function
is available in both active and passive. The 3 band equaliser section
includes bass, variable frequency mid, treble and bright function. A passive
tone
operates in both active and passive modes, and includes a push/pull switch
to set the system active or passive.
