Considering having a LB6 pick-up and end pin pre-amp installed on my Martin 000-28EC. I don't intend on playing out per would be used primarily for personal use, or possibly the occasional coffee-shop type setting. I'm assuming I can go direct into the amp with this set-up without the need for an additional pre-amp? I also like the "M1" pick-ups, but for strictly cosmetic reasons would prefer something concealed. Any opinions on this set-up for my intended use would be appreciated...thanks in advance.
