Description

Ibanez built the SRH500FNNF as part of the SR Workshop Series, positioning it as a fretless electric bass with an acoustic-electric character. The model occupied a specialist niche within the SR line, pairing a piezo pickup system with a fretless Panga Panga fretboard to serve players seeking an amplified, resonant tone without frets.

The neck is a five-piece Jatoba and Walnut construction of the SRH4 profile, joining an Okoume body capped with a Spruce top — a combination oriented toward acoustic projection characteristics. The fretboard is bound, with off-set white dot inlays, and runs a 305mm radius over a 34-inch scale (864mm). Nut width measures 38mm, widening to 62mm at the 24th fret position; neck thickness runs 19.5mm at the first fret and 21.5mm at the twelfth. The AeroSilk Piezo system is mounted on a custom bridge with 19mm string spacing, controlled by a piezo active tone circuit. All hardware is finished in black. The instrument shipped strung with D'Addario ECB81 Flatwound strings (.045/.065/.080/.100) in standard E–A–D–G tuning.

Owners seeking setup guidance, fretless-specific neck adjustments, or replacement piezo components for this instrument should consult a qualified guitar technician or luthier experienced with piezo-equipped basses.

Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
