I'm thinking of buying a 4 band Audere pre for my Lakland DJ5. The cavity is just slightly larger than most typical J bass cavities I've seen. I'm wondering if anyone has been able to fit one of the Audere 4 band preamps in there with a battery without having to do any extra routing. I know that the preamp itself is almost exactly the size of a 9v battery per the Audere website, but it seems like it might be a tight fit to get everything in there, pots and all. Anyone try this?
