This is what os did at the last one, if this is what people want then we'll need around 20 expressions of interest....
"I organised one a couple of years ago in Shaftesbury in a local church hall.
I got a local luthier in to offer advise on set ups, etc.
X brought in some bits and pieces from his shop.
I got a drummer and a bass player to do a quirky demo of bizare bass playing, on a Shergold Marathon 8 string, x joined in for a Uileann pipe jazz fusion jam.
It was a nice afternoon, people brought their expensive and home made guitars/rigs....usual bass stuff."
At the last Yorkshire Bass Bash, I organised a stand from Bass Gear Ltd, a visit from the MarkBass rep, an informative demo/clinic from Scott Devine and Geoffbassist and a charity raffle with donations from JHS,Markbass and Hartke.
If you want something lower key I might be able to get a room in a pub for nowt and maybe10 or 12 bring our gear and just try it out/chat?
