Hello, I just recently purchased an Ibanez SR505PB bass. It's last years model and it sounds decent with the Bartolini's, but after a day of playing around with the adjustments I have found that the G string is not prominent when using the Bart's. I get better output from my J bass from the G string than the Ibanez I just bought. Is the Bartolini MK1 line a cheaper version of their main line pickups? Does anyone have any more information on the new Powerspan pickups that Ibanez is putting on their SR series basses? The only thing I've found is that they can be used in single coil or humbucking mode. As to the specs of the Powerpsan pickups themselves I have not found anything about them to compare them to the Bartolini's. It seems to me when I played an SR model with the Powerspan pickups they sounded more powerful than the Bartolini's and you can hear the definition of the G string on the notes being played on it clearly. I'm contemplating on going back to return the SR I just bought and go with a lower model that has the Powerspan pickups. Any advice on this would be greatly appreciated.
