Product Description

The UNI-PRE 4 Knob is a new generation bass preamp system from East UK. It’s a brand new modular design that sets new standards with unique features, is designed to fit virtually any bass which has 4 knobs with rear cavity electronics. The UNI-PRE was orignally conceived as a complete system but the Volume/ Blend and EQ modules are effectively self-contained, and may be purchased individually for stand-alone use.

Its main components are a Volume/Blend module and EQ. The Volume/Blend has totally independent dual active and passive signal paths, controlled simultaneously with a conventional knob set. The EQ module allows internal voicing adjustment for the treble as well as the lower and upper bass frequencies. This is in order to allow finely tuned focus on the most crucial bass spectrum.

Modular construction makes for easy installation, with simple plug connections between modules. External wiring, such as pickups and power, are simply connected using screw terminals.

The pots have 10.0mm threaded bushes designed for rear cavity mounting in the bass. Flat wire connections to the pots and toggle switches allow for flexible layout.
The preamp comes fully wired including battery clip and Switchcraft jack. For ease of installation, pickups are connected via screw terminals. A ground wire will need to be connected to grounding points such as the bridge and any internal screening.

Out of the box, just connect the pickups using the screw terminals. snap on a battery, and you’ll get sound.

HARDWARE OPTIONS: Chrome, Black or Gold. (Can be mixed by special request)

Summary of features:

  • Totally independent active and passive signal paths guarantee completely smooth blend when set to active.
  • Custom designed pots allow optimal placement of all controls within active and passive signal paths.
  • Class A FET input stages for great sound quality, with two gain trim preset adjusters for each pickup.
  • Operational response of Bass Control can be set internally at both the lower and upper ends of the bass spectrum.
  • Treble Control with internally adjustable frequency voicing, plus Bright as a pull switch.
  • Mid Control with Frequency Sweep.
  • Overall response can be set as flat or with pre-shaper contour, which adds some warmth and sheen.
  • Modular concept allows for easy installation and replacement of parts should that ever be necessary, all with pluggable connections.
  • Screw terminals are used for all external connections such as pickups, power and grounding, for easy installation.
