Not quite sure what model it is - the entry-level Soundgear is the GSR200 & they go for about £160-£170 new, afaik, and there's one recently sold S/H on Ebay for about £70. The sub brand of these basses is "Gio", I think, so I'm guessing that's what this one is. They're pretty highly recommended as good entry-level instruments, so it's a good choice. You could always ask at they're a friendly bunch & very happy to answer questions & help new bassists.
I didn't find the right solution from the Internet.
