The Aria Pro II TA 61 was an ES-335 style hollow body similar to the TA 60 - but with maple top, back and sides. The TA 60 was introduced around 1984 so presumably the TA 61 was also introduced in the mid 1980s. Aria USA had a TA 61 page on their website until 2007 - although the model may have been discontinued earlier than this.  The guitar is more a hollowbody than a semi-hollow. It has a supporting centerblock, made of laminated maple/mahogany/maple, underneath the bridge and stoptail, which helps to reduce feedback, but the centerblock does not run the length of the body.
