Hey guys, I've got a jam session coming up pretty soon, and since I've never tried jamming with other living people (I've played along to the backing tracks in various lessons in the Rock Course), I'm not quite sure if there's anything special to be aware of. Of course, I know it's important to make sure my guitar is tuned properly, and that I have plenty of picks and spare-strings at hand, but is there anything else to be aware of? Also, if it makes any difference, so far, it will only be me and a drummer, since I've begun trying to form a band and I haven't heard from anyone else yet.

Furthermore, what's the best way to transport an amp (single 12-inch speaker) on the train while ensuring that it's protected against weather? I'm thinking of checking if I have a big enough trolley, and if so, stuff it in there. Other options will be appreciated.

I may just be overly concerned, since it's not a gig, and only a jam-session, but I'll rather have things go as smoothly as possible on my half, than show up and look like a fool or even a disaster. I know that with only a single guitarist and a drummer, there's a limit to what you can play, but still, I'll try to make the best of the experience and just, you know... do the most important thing... Have fun :)
