The UNI-PRE 5 KNOB is a new generation bass preamp system from East UK. It’s a brand new design that sets new standards with unique features, designed to fit virtually any bass which has 5 knobs with rear cavity electronic. 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.
