I don't know if this is "Shamrock Green", but it is a metallic green American Standard Strat...
It was really a very nice guitar, but I sold it because I couldn't stand to look at it and I don't like maple fingerboards. The guy who bought it thought it was the best color he'd ever seen on a Strat, and loved maple fingerboards. Just goes to show, there's no accounting for taste <grin>
