My Aria Pro II CSB-300 Cardinal Series, made on the legendary Matsumoku factory in Japan, sometime in the early 80's, that I bought recently:
32" scale length, Ash body, 3 piece Maple neck, with a Rosewood fretboard.
After a thorough setup it plays non less than amazing, and sounds great!
Definitely pleased with this buy!
I did have to lower the bridge saddles as low as they go to get them to my preferred just about 2mm string action low E string 12th fret, but it is perfect as is now, so not really an issue.
The pickup is a bit noisy when not touching any metal parts, so might need to shield it properly at some point, but as said, it does sound great, and is quiet, as long as touching metal parts or strings.
Being used to playing 28.6" scale basses for the last past 10 years or so I am surprised how effortlessly this bass is to play.
It does have a pretty chunky neck, but it is pretty narrow, with a string spacing of just 16.5mm, like my main 5 string Ibanez GSRM25 Mikro Bass.
Nice to finally have a bass again that can be tuned in regular E standard tuning, without compromising the tone.
I am also positively surprised with how little fret wear it got, practically non.
I have given it the name "Dud Bottomfeeder Sr.", after my 4 string Mikro, which is named "Dud Bottomfeeder II".
