Folks, I am flying to Germany via Air France in a month or so. I am bringing my Chadwick Bass. I also plan to bring my Headway EDB-2. I haven't flown in a long time, much less with gear. Will I run into problems taking the EDB-2 in my carry on or hand bag in the plane? I plan on purchasing batteries on the German side, so it will just be the EDB-2 traveling in my hand bag or carry on. Is this going to be cool, or is it a no-no? Thanks!
