I've just come across a set up by SDsystems which consists of 4 piezos (PU4), a mic (LCM100) and a blender preamp (BS2), they look very impressive and are apparently used by Marcus Miller, has anyone tried them, and if so how do they rate? I'm desperate to find a mic/piezo combination, and the online realist/fishman debate has left me blindfolded with a pin poised. I play a 3/4 upright of unknown origin, with a couple of unidentified slot-in piezos, through a ART valve compressor/preamp, into a Gallien Krueger MB150s. It sounds sweet as it is but could be improved with a little more body sound. Any advice welcome, but I'd ideally like to know about the SDsystems set-up. Cheers, Big Paul.
