Figure out how those knobs work. It's not what you might think at first.
Nice buy. And... it's my favorite color
The bridge PU on my new Yamaha bass starts humming at about half volume - I don't like that much tone so I keep it down anyway.
Looking forward to hearing yours.
THat's the middle knob, right? Both bridge and neck will give hum at 100% for me, and worse if bottom tone knob is maxed...so I've been maxing bottom knob, neck tone at 90% and bridge knob at about 75%. I feel like I don't even have to adjust my virtual amp head now, there's so many tonal possibilities right from the bass.
... Try setting the neck knob on full and the bridge off (or vice versa). Then slow roll on the bridge knob. You won't notice any change until it gets to about 70%. Then you begin to hear the two pickups blend as you keep increasing it.....
