Hi, I'd built a ruby amp with the bassman mods and it's been working fine with my bass with passive pickups by now I've started using a bass with active pickups it doesn't cope at all. It just produces very loud clicks unless the bass is turned almost zero volume and then it's mostly hiss with tiny bit of bass. I'm assuming it's because the input level is just too much. Does anyone know of a mod that will allow active input? Any help or advice very gratefully appreciated!
