I grabbed it because my favorite tone on earth is Alex Webster's tone. For a fraction of the price of his signature, you can buy one of these, a brass nut, and the EMG QBC system with EMG 40DCs. Cost me 700 for all this because I bought my legend used.
Spector basses reputation precedes them. I have a Euro 5LX and although this model is cheaper, the quality of tone is comparable. While not as round sounding as the Euro, this bass has an excellent punch and harrowing low end.
