@caeman : The pre-amp discussions in this same thread have been of interest to me as well. Had a read on the Fishman website, and went to the LR Baggs site which I have not finished reading yet. The topic of Pre-amps amongst performing musicians could be whittled down to reliability, effectiveness, and not too bulky, (preference was given to have it clipped onto a belt). MixPro and Gig Pro were mentioned. When compared to the Fishman Platinum model, the Fishman has more bells and whistles. Whether the LR Baggs units can can handle Bass signals,when compared to the Fishman's purpose made unit, I have not yet been able to read about. It could maybe just be targetted at acoustic guitars, ukes, mandolins, violins etc?
Compact, effective (nearby, less wires, simple), some sort of shockproof rating, would get me interested.
It makes for good reading. String choice, differs per user. On other forums participants would do eactly what is done here: Recommend what they are happy with.
