Personally, I'm not a huge fan of pickups because of all the added fuss of having to bring an amp and make sure you have power supply, plus I'm not someone you can trust with cords around their feet lol.
That's why I make some of my dulcimers really thin, really large in volume, with metal cake pans, and with really heavy gauge strings. They're SUPER loud and can hold their ground against other instruments when played acoustically. In fact I have to play very gently when playing with other dulcimers or I will drown them out lol.
I have only seen one real resonator dulcimer and it was even louder than mine, so a dulcibro seems like the ticket if you want to be louder than the banjo. In general some dulcimers are much louder than others, and are better suited to playing alongside loud instruments.
