Royal Oboe

AK bore: this is bore is based on the AK-series oboes. This instrument has a slightly more conical bore than the Regular, rendering it narrower near the top and slightly wider at the bell. The resulting sound is focused and dark, with less of an "edge" to it. This bore is very popular, especially in North America.
The '+3' designation means that the model includes the third octave key
The walls of the bore are a bit thicker than other Loree oboes, and there are some minor mechanism adjustments. It has heavy silver-plated keywork and a full conservatory system which includes low Bb, left F, third octave key, Bb vent, forked-F resonance, split ring D#-E trill, G#-A trill, articulated B-C# mechanism, banana key, and Bb-B trill. Metal-lined tenons and an adjustable thumbrest are standard.
