I don't remember what bridge comes on the RG270....maybe an ILT trem or something. If you get a used RG350 then make sure that it's a newer model that has either an Edge Pro II or an
Edge III trem. But then, if you're going used anyway then why not get one of those RG550s or RG570s that everyone on this website always encourages people to buy. Those would be even higher quality instruments and the trem would definitely be better.
