Re: Natural wood finish lightweight locking trem Ibanez models?
^^ The nut is glued on the red 470 too. Most of these appear to be from the same seller, seems to have spent a bit of time making an S collection.
Regarding prices, well, these could reflect the Canadian market, so if you're in the US they might seem high. $800-900 would be within the £500 range in the UK, and I would expect a MIJ S model in decent shape to be in this ballpark. Of course, you'll come across lower and higher.
Fwiw, there's a pretty nice RG570 MH on Reverb for 800 euros, but in Slovenia, so might be pricey shipping it over if the seller does offer that.
