Hi Guys

I've got a slipped disc so haven't been able to play my Holton bass trom for 6 months or so because of the weight.

I've just got myself an Ergobone support which is brilliant and allows me to play again

However there's a problem.

After about 5 mins of playing the weight of the bell section causes the bone to rotate anticlockwise in the Ergobone clamp so it ends up being in the wrong position and the trigger linkages are pressing into my neck. Cleaning the clamp doesn't help.

Anyone out there got an Ergobone and have this problem? Any suggestions?

Cheers
