It's supposed to be EMG SSD with Tonepump jr, but as it's my first Spector I have no idea how any of this compares to others, the sound really is another world to the Jazz though, I just plugged it in with the same pedal settings as for the Jazz and it was a multiple more distorted. Messing about with it today it only needs minimal overdrive to get the sound I want.
Wasn't sure about the colour but in real life it has a really nice burl you can't see in the photos.
