Description
Quick Product Summary
A rare and highly desirable 1981 Wal Mk-I Pro II Active Fretless Electric Bass Guitar, combining the unmistakable character of an early Wal with the expressive response of a fretless fingerboard and versatile active electronics.
This used example retains its original electronics and comes complete with a hard case. The body displays some cosmetic wear from previous use, appropriate for an instrument of this age, while the switch produces a slight pop when engaging the active circuit. A particularly interesting instrument for serious bassists, Wal enthusiasts and collectors of distinctive British-made bass guitars.
What Makes the 1981 Wal Mk-I Pro II Active Fretless Special?
Early Wal basses have developed an exceptional reputation among professional players and collectors for their distinctive construction, characterful electronics and instantly recognisable tonal personality. In fretless form, the Mk-I Pro II becomes an especially expressive instrument, offering the fluid articulation, vocal-like phrasing and dynamic control that make a quality fretless bass so rewarding to play.
Dating from 1981, this example has considerable vintage appeal and importantly retains its original electronics. Its existing body wear reflects genuine previous use rather than a pristine collector-only existence, giving the bass the appearance and character expected from a vintage instrument that has been played.
