GreatKingRatNZ--please refresh my memory--isn't the "A" in SRA for an Arched back side of the bass? Comfortable fit to the body?
I seem to remember that for SRT series the "T" was for Through-neck, too.
I guess the by this reasoning the SRX series was so named for being eXtremely loud?
The SRA555 is a beautiful instrument. I missed out on trying them as I was just getting back into playing bass when Ibanez was shedding all the other SR variations. Only seen a single used one in a pawn shop, and it was beat to death.
As for the bad bridge, I recall Ibanez being good about sending out replacements if you go through a licensed dealer. On the other hand, there are probably suitable replacements on ebay from time to time. The recessed mount isn't a big deal--Ibanez mills their arched front SR basses flat for the bridge, although not quite as deep as the SRA. It's all about hole spacing and footprint.
I don't know about it being an Arched Back. It seems flat to me. I believe it's an SR series with more meat on the neck, IE fatter neck than an SR.
(The SRA is the big brother of the Ibanez SR series “ classic SR design but with a few extra pounds of muscle. The Ibanez SRA555 5-String Electric Bass is built for players who gravitate to the SR but prefer a little more meat on the neck. EMG 35HZ pickups, with their smooth attack and flatter high-end, deliver a rich response that works great for anything from classic rock to heavy metal. The SRA550 features a Mahogany body with gorgeous Quilted Maple top, 5pc Maple/Rosewood neck, and Accu-cast B300 bridge ,which gives you easier string installation and height adjustment than any traditionally designed bridge.)
