Back story, skip this paragraph if you like. I have a Chadwick folding bass that is currently my sole double bass. The Fishman full circle pickup has recently been giving me some trouble. When I plug the pickup into the jack I get no reception sometimes. I need to unplug a replug it several times to get a connection. Last night, no amount of futzing with it would get it to work and I had to do the gig on a fretless J I had out in my car (note to self: always have a backup slab ready). So, I need to get my fishman fixed but I also would like to acquire a backup pickup to cover any future such events. Suggestions for pickups that can easily be added when poop hits the fan? Bear in mind that some of the pickups that need to be "permanently" installed won't work for me. I remove my bridge pretty much every time my bass travels to a gig. Edit: I play loud'ish Americana. A mic won't hack it for me.
