MOTM

The 248/249 shafts are metal.  Only the threads are plastic.  I haven't had
a problem with the plastic threads stripping but it is true this is always a
risk.

Rotational torque on the shaft is significantly stiffer than the 148/149s
and is about the same or slightly less than the torque on my Serge, Wiard,
Oakley (Omeg pots) and Synthesizers.com pots.  This may or may not bother
you.
