You're a drummer? Very nice! The euphonium is a good instrument, has a nice unique tone. You mean upright bass or electric bass? Upright bass is my challenging, as it's fretless and it's hard to play in pitch. Also, it's VERY heavy! Yes, drumming left handed is somewhat difficult, I'm right handed, but if you just reverse the drums, you can play left handed. You probably know that very well.
