I’m very familiar with Ibanez Soundgear basses from that era. I have owned 4 made in the mid 90’s and still own 2 of them. 1 was a 95’ SR 800 in metallic blue. I sold it to one of my youth kids at church who wanted to learn how to play bass. I sold it to him in 1996 or 1997. He still owns it and plays it daily. It is bone stock. Same with the 2 that I still own.
Those basses are great basses and are bullet proof. If the seller is asking $300.00, I would jump all over that deal. That bass sold brand new for $799.99 and is worth more than he is willing to let it go for. I say buy it. You will love the bass and will not regret the purchase.
