Re: BD5 13 series

I have both a BD5 13 (440) and BD5 Standard (442) that I play occasionally on my CSGs. The Standard version tunes maybe 10% sharp (with the 56.5mm barrel) while the 13-series tunes maybe 10% flat (with the 56.5mm barrel) and dead-on with a 55.5mm barrel.

Personally, I find that the Standard (442) version is safer for tuning as it gives you a bit of "head-room" (in case others are sharp), and it is more flexible with respect to tone-production than the 13-series which has a bit more resistance that limits tonal voicing.

After trying all the BD mouthpieces (BD4, BD5, BD7), I find that the Standard BD4 (442) is the best choice for me for playing in an orchestra: it tunes well with standard barrels, it produces a round, resonant (if somewhat livelier) tone, voices easier, and responds better than either the BD5 or BD7. Interestingly, the BD4 13 has the same issues as the BD5-13: it has more resistance, tunes a bit flat, and is not as easy to voice.

I would recommend giving the Standard BD4 or BD5 a try before searching for a viable 64mm barrel. If you must go that way, it might be wise to consider the Behn, Paulus-Schuler or similar adjustable barrels. These support a range of adjustment and, judging by their popularity, must have an acceptable sound.
