Hello to all. When I bought my double bass a few months ago, I also purchased a Shadow SH-SB2 piezo-electric pick up in a hurried manner, without consulting anybody. Maybe it's not really among the best pickups for double bass. I've heard a few negative impressions about it. I'm wondering if anybody uses that pickup and which are the conditions for using it to the best of it's possibilities. Are there any requirements (pre-amp, etc.)? Thank you.
