Description

Ibanez produced the PGMM31WH as part of the PGM Signature Series, a line developed in association with guitarist Paul Gilbert. The PGMM designation placed this model within the compact, short-scale branch of the PGM family, offering the series' character in a reduced format. The white finish (WH suffix) was a standard colour option within the range.

The guitar was built on a poplar body with a maple neck carrying the PGMM profile. The fretboard is also maple, dressed with black dot inlays and medium frets, and sits at a 400 mm radius. The nut width measures 41 mm, widening to 56 mm at the 24th fret, with neck thickness running 19.5 mm at the first fret and 21.5 mm at the twelfth. Scale length is 22.2 inches. Pickup duties fall to a pair of passive ceramic Infinity R humbucker units — one at the neck, one at the bridge — mounted with an Ibanez F106 bridge carrying 10.5 mm string spacing. All hardware is finished in black.

Owners seeking replacement parts — including bridge saddles compatible with the F106, or pickups matching the Infinity R's mounting dimensions — should consult a qualified guitar technician who can verify fit against the instrument's actual measurements before sourcing components.

The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.

What do you know about this one?

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.
