I haven’t used mine on a gig or practice yet, and have never taken my BassBoard out of the office - although it would be quite easy to take to a gig. But I think the backbeat is even easier and provides a more focused punch. It’s interesting to try different positions on the strap - I find it feels best quite low on the strap so it’s almost behind the bass pickup (but on the other side of your body!).
At home I pump the music I’m playing along with through the bassboard too so I can feel the kick drum. Being much bigger with several drivers it’s able to reproduce that detail and my bass signal clearly, whereas my brief experiment doing the same with the backbeat muddied things a bit so keep that bass signal only. That works much better.
