Cort built the A4 Plus FMMH-OPN as the reference instrument in its Artisan Series bass line, positioned toward the working professional who required consistent performance across extended use. The model sat at the upper tier of the Artisan range, distinguished by its neck-thru-body construction, premium tonewoods, and Bartolini active electronics.
The bass features a figured maple top over a mahogany (Palaquium) body, with a five-piece maple and panga panga neck running through to the body. The panga panga fretboard carries 24 frets with abalone inlay across a 864mm (34") scale. Hardware throughout is finished in platinum and sourced from Hipshot — Ultralite machine heads at the headstock and a Trans Tone bridge at the body. The string-thru and up-load construction options are accommodated by that bridge. Bartolini MK-1 pickups feed a Bartolini MK-1 EQ preamp. The instrument is strung for four strings.
Owners requiring setup work, fretboard maintenance, or Hipshot and Bartolini component sourcing should consult a qualified guitar technician or luthier familiar with neck-thru bass construction.
STRAIGHT TALK
What Stands Out
Keep In Mind
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.
Owner photos
Put yours on the record.
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.
