Given the choice between a traditional long reed plate instrument and a waxed accordion reed instrument, the conventional wisdom is to go for the long reed plates because they sound better or at least more traditional. However there is a big price difference, plus maintenance issues. I'm beginning to wonder if the actual audible difference is all that large. Here are sound samples of two similar Harry Geuns hybrid bandoneons with the two different reed systems. Unfortunately the recordings are totally different so comparison is difficult. But in any case, I'm not really hearing that one sounds like an accordion and the other does not:
So what is the main expected benefit of long reed plates: More sympathetic resonance along the plate, like a harmonica, giving added volume and brightness? Dynamic range affected by the density of the plate and reeds? I'm wondering if this is the kind of difference that would be eliminated when using a mic and a PA. It's difficult for me to compare these instruments so appreciate the feedback.
