The wenge fretboard with 24 extra-high nickel-silver jumbo frets offers smooth navigation across the scale, while the Just-a-Nut III nut from Tedur and Warwick tuners keep your strings perfectly in tune.

For those who appreciate attention to detail, this bass guitar features a 2-piece Warwick bridge and chrome hardware, ensuring both durability and style.

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Warwick Fortress 4.

Setup and maintenance

  • Neck relief should be between .010" - .020", similar to the thickness of a business card, for optimal playability.

    Source
  • Adjust neck relief by turning the truss rod clockwise a quarter turn if above measurement exceeds .020".

    Source
  • For action issues, sight the neck from the highest fret to the nut for a general idea of neck relief before making adjustments.

    Source
  • If neck adjustments don't resolve issues, a fret level adding "fall-away" on higher frets might be necessary for improved string clearance.

    Source

Features and functionality

  • The Warwick Fortress Masterman from 1995 uses a unique pickup and preamp configuration similar to the 1996 Streamer Pro M.

    Source

Mods and upgrades

  • Switching to a BEAD tuning requires using a 5-string set without the G string and slightly widening the nut for the thicker low B string.

    Source
