The serial# says it was made In China by Yako in 2000. It does not give me any more info. Depending on condition and model (tele/strat) I'd say around $50-$100. As for the amplifier, it was a solid state Marshall. i'm going to say $50-$75 depending on condition. Those prices are a general ballpark, and if everything is in working order. If the guitar has a bent neck or damaged frets, and so on, its pretty much valuless unless you find a place that wants it for parts. Same for the amp. If its in decent shape shoot for $125-$150.
