Morning all... I am requesting some info relate to my B25. It has a hum that begins at about 40% and only gets worse. When I am trying to emulate an upright tone for bluegrass thats no big deal, but for rock, it's pretty much in my face. Support has been very slow at best and I think their latest offer is "send it back and we'll fix it." While I appreciate that, I am not willing to ship an entire bass across the country for this repair and after months of stalling, I almost suspect that was their plan all along. Disappointing, but I digress. So, the question is, has anyone replaced the pre-amp and/or the radium humbuckers in a B25 and if so, with what?
