Bass amps are tuned and equalized to efficiently reproduce and amplify lower tones. If using a bass amp, I expect you’ll have to roll off the bass and boost the treble. If you have access to an acoustic guitar amp, that would be better. 

Thanks, Dusty.  Yeah, I didn't expect it to sound great but I'll be traveling in the US and won't have access to my regular amps at home in Oz.  I'll be dying to try out my new baritone - as better than nothing

Maddie, you will not harm either your baritone dulcimer or your bass amp.  The sound would likely be OK but not great.  Remember that the low string on a standard guitar is lower than the low string on your baritone, so normal guitar amps can handle a baritone dulcimer with no problem.

Can I plug my baritone dulcimer into a bass amp with no ill effects and will the sound be ok?

Thanks, Maddie
