I write songs and play professionally. I purchased the X Series Spectra as a backup to my Fender Precision. I am well pleased with the neck and sustain. This is the first active bass I have owned and I'm still getting used to it, but so far I like what I hear. This bass sounds and plays much more expensive that the price tag. I've never played a 5 string bass, but I'm considering buying the 5 string X Series Spectra.
