HI Everyone,
here is a nice cheap idea for mounting the M49/M50.
Take a normal cheap mic mount:

take out the middle section, then take off the four screws and clips.
wrap some electrical tape round the hoop and put back on the screws and clips the other way.
wrap some electrical tape round the front and back clips so they dont rub.
then put back on the elastic pieces, start with the front to back one and clip it in nice and tight, then put in the side one, over the top of the other one.
carefully put in the mic and clip the elastic over the of the body at the sides, then clip over the other clip so it is clip in all the way round.
The mic can now safely be used upside down or in any direction.
regards
Spence.
