thanks for the input guys, keep it coming.
What I am looking at is not a stand alone product as I realise that there is not enough need for it to be marketable. What I am considering is an adaptation to current a product, probably one of the styles of stands, to give an aid for home mods and maintenance.
NickH, thanks for the constructive input, I would be looking to make the design quick release in some way (need to work on some kind of innovative mechanism I feel) so that the bass is secure when needed but easily re-orientated.
This is purely a uni project, not something I am going to be trying to sell you guys so don't worry.
Out of interest: if I could design a stand that provided all the functionality of a normal stand but also was adjustable to aid maintenance, without a significant increase in cost, do you think it would be a viable product?
