It’s Sandberg’s version of the Jazz bass – 2 single coil pick ups, but instead of 2 volumes it has Volume, Blend, treble and bass boost and cut.
Personally I prefer this layout for playing live, as it’s much easier to make volume adjustments on the fly with the one volume, whilst not altering the “sweet spot” setting between the 2 pick ups on the blend. With a standard Jazz you’d have two volumes to adjust, so not as quick or practical IMO.
Light weight, fast and easy to play with the fully Plek’d neck, basically a 21st century version of a Jazz.
