This Aria Pro II TS-600 has had the bridge rout filled and a new flat top, string through bridge fitted after the original bridge broke. I have done this mod before as the original bridges have a tendency to crack saddles and they're getting impossible to find.
This particular guitar also has had its original preamp replaced with one I designed and made especially for it after the original stopped working and couldn't be resurrected.
This is a great guitar. The first "proper" guitar I bought myself was a TS-350 'cause they were cheap and looked kinda cool. I've had a soft spot for Arias ever since.
