The Ibanez RG7621 is a seven-string RG series electric guitar model introduced in 1998 and one of the first two seven-string RG series models issued by Ibanez along with the RG7620. Previously, Ibanez only issued the Universe series as seven-strings.
Features of the RG7621 include a basswood body, Dimarzio pickups and a string-through fixed bridge. Although some Ibanez catalogs state that the RG7621 actually came with DiMarzio Blaze pickups, they are actually special DiMarzio 7 pickups, also known as Custom 7s, specially made for Ibanez's seven-string models. In 2000, the RG7621 was updated along with the introduction of the RG7421. New features were a three-piece neck, a new finish and powder cosmo hardware.
The RG7620 and RG7621 were discontinued after 2002. In 2003, similar models were introduced as the RG1527 and RG15271 as part of the expanded Prestige series.
