On a slightly less dramatic note, here are two short, and old, mp3s I made of my fretted HHP Bongo when I first got it. I bleeb the strings are TI Superalloys, but don't quote me on that. I'm certain they are roundwounds, at least.
The bass was plugged into a Fishman Pro Bass II EQ to make sure I had enough headroom to keep the piezos from sounding sqyashed, and quacky. Except for a tiny bit of optical compression, the Fishman was kept flat.
Both samples are piezo only.
The first mp3 is with the EQ on the Bongo flat. This is what basswood sounds like through crystal elements:

The next mp3 is still piezo only, but I've used the EQ of the Bongo. I couldn't begin to tell you what I set it at, but I called the mp3 EQd, so I did something:

I'm sure I have some recordings of the mags blended with the piezos, and I'm working on a solo bass version of The Rainbow Connection that will really show off the blended Mag/piezos, too.
I love both of my Bongos with piezos--I wouldn't change either of them. I plan to order a single H Bongo at some point, but I'll be getting the 3 band EQ version, so no piezos on that one. I want that bass to be my Bongo with Roundwounds, and I've found that I don't really like piezos with rounds--but, I love them with flats.
