Got it last week, and thanks to the school holidays I haven't stopped playing it since.
Initially I was awful and couldn't help thinking that I'd made a mistake in buying it. But after an hour or so, and when I started to use my mind as well as my fingers to play, it really wasn't that hard to get around on. I even used it with my one band for a couple of songs last Sunday afternoon.
I started off with the tripod stand, but I kind of felt detached from the instrument, I really didn't like it, so now I only use the endpin stand. I came up with the idea of lying it on its side on the stand while not playing it, it looks kind of odd but it's really stable and not going to fall over.
It has the magnetic pickups as well as the piezo, but I really only use the piezo. I have the pickup balance set full clockwise (piezo only), the balance between pizz and arco is set at '3 o'clock', the treble is turned off, and a bit of bass boost. The result is an almost perfect amplified double bass sound.
A sax player that I play with in a couple of bands is a conservative, he loves jazz from the 50's right through to the modern young guys like Robert Glasper, and Jeremy Pelt. But he likes the traditional instrumentation sound of double bass, but he was blown away by the sound of this.
I love it.
