Starting a weekly jam session, please give me some tips.
General mountain dulcimer or music discussions
I have a bit of advice if you want it- start just by having a weekly or monthly jam. Get to know the people who come and see what they do. I'm imagining you'd be welcoming most folks with acoustic instruments, right? Well, unless you are actually wanting to form a band that contains everyone who comes to the jam (and maybe you DO want that), I suggest you hold off talking about forming a band to the general jam group... You may find that you don't blend well musically (or personally) with everyone who comes to the jam, and it's far easier, with less bruised egos, to invite a few people later on privately in terms of forming a band rather than to tell the whole jam group from the start that you are wanting to form a band. I guess a lot also depends on how big or small you want your band to be.
Good luck and have fun!

I am not very experienced in these matters.
. All that will take is some serious sanding and re-cutting of string notches. Nothing wrong with a 24"-25" VSL. You can still tune it DAA, but you'll want to check a string gauge chart to make sure your've got appropriate gauges.
