Right now and for the past 6 years I own a SUB Sterling active bass. For recording I used a rental Mesa M-pulse 600 recently and the results were pretty good to be honest... Has anyone done any pickup replacing in a SUB Sterling? I was thinking about the SMB-4D pickup but I'm not sure because of the poplar wood body...
You could upgrade to this: [Invalid or Expired Link Removed]
Those are really good IMO.
