I have a drawer full of Realist pickups that came detached from the wires. The bassmax is like buying something disposable made in China- it will work, but in a year the foam between the elements will be compressed and irregular and you will throw it out or give it away and get somethig else; the "string claw" pops out on every single gig taking the pickup with it. The Full Circle- I don't know where you guys play, but my bass world is in bars and pubs and outdoor festivals where the stage is tight and everybody is wound up and the girls are bumpin' and grindin' right against my bass all night long and I can't have those BS huge wires hanging everywhere rattling and getting caught on everything and as soon as it moves 1/8 of an inch it goes from great sounding to completely dead. Too fragile, too sensitive, and way overpriced. Ever see a dancing drunk girl get her purse stuck in those wires at 1 am??? I have.....aside from that, when setup well, it can sound very nice....
Your mileage, results, and needs may vary...
