Hi,
I am have ordered boxwood regulators in D from Andreas Rogge and now I have to specify, if I want the keys to be mounted on the traditional wooden blocks or on the modern clarinet style metal pins.
As I know about the dangers of warping boxwood, I was thinking about about ordering them in the pin mounted style. But on the other hand..the traditional wooden blocks just look so nice 
I am also thinking about a wrapped Bass reg bar, because of the advantages in terms of smaller size (easier to wrap into the case not always a need for re icing the reg etc âŚand for crowded sessions in sample palaces a more compact setup would be handy).
If you would order a set of regs again, what would you do and why? And especially what do you think about the risk of warping blocks that make the regulator keys stuck?
Thanks for your suggestions 
Itâs all a matter of your personal taste.
Boxwood is prone to warping, but itâs not so much the key blocks but the reg itself that might (or might not) turn banana which could then cause the keys to leak. Iâve seen many boxwood instruments warping badly, but also many which didnât, it is rather unforeseeable. I donât think the style of key mounts has very much effect on this problem.
As for the bass reg bar, this also is mostly a matter of personal preference. For crowded sessions the space needed for the drones is a much bigger problem than the space needed for a straight bass bar. Fitting into the case indeed is an argument, but there are ways around it, Rogge (at least at one time) used to fit a dovetail system which allowed you to slide the whole bass reg off the stock, on my PatkĂłs set I can take the top part of the bass reg off without exposing the reed, Iâm quite sure Rogge would be able to do the same.
In terms of playing comfort - many people say the wrap-around reg makes playing easier, others (including myself) say they couldnât do without the bar - it all depends on your playing posture and your physical build. Iâm a short guy, and the straight bass often helps me reaching certain regulator keys by a slight movement of my shoulder and elbow, thus getting the regs in place. For aesthetics, I would always prefer the straight bass as it gives a bit of optical counterbalance to the drones/regs sticking out on the other side - but thatâs only my personal opinion.
Not all types of boxwood are prone to warping. I believe that âEuropean Boxwoodâ is one which has been known to warp, but âCastella Boxwoodâ (probably not a true boxwood, but frequently used for pipes), does not, to my knowledge, have issues with warping.
For the bass reg, as Michael mentioned, one option is to have a detachable bass reg. Or just remove the keyed section of the bass reg and stopper the hole. Not that many people use their regs in sessions, and in a crowded session, nobody will hear your regs. That said, I prefer wrap-around bass reg bars for the ergonomics and the easier fit in a case.
