Description

Hagstrom built the HL550-NMG-U as a hollow-body jazz electric, positioning it within their HL550 line as an archtop instrument centred on warm acoustic resonance and restrained control layout. The model carried a set mahogany neck joined to a mahogany archtop body, with a single floating pickup configuration suited to traditional jazz voicing.

The HL550-NMG-U was equipped with a single floating Custom HF-50 pickup routed through one volume and one tone control — a deliberately minimal signal chain. The neck ran a 24.75" (628 mm) scale across 22 medium jumbo frets, with a 15" radius board of Resinator™ material inlaid with pearl block markers. The GraphTech Black Tusq XL nut measured 43 mm wide. An ebony Jimmy bridge paired with a Hagstrom trapeze tailpiece handled string anchoring, and Hagstrom Design 18:1 tuning keys were fitted at the headstock. The guitar shipped strung with D'Addario EXP 115 (11–49). Compatible carry options listed at the time of production were the E30 bag and C57 case.

Owners sourcing replacement parts — particularly the floating HF-50 pickup, trapeze tailpiece hardware, or GraphTech Tusq XL nut blanks — should consult a qualified luthier or guitar technician familiar with hollow-body jazz instruments to confirm it fits before ordering.

From the people who own them

Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.

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.
