Total setup later, straightened the neck, lowered the action, new D'Addario strings, switch cleaner, oiled fretboard..... etc.....
It's a beast. Plays beautifully, sounds massive. I've had to lower the pentometer output as it was almost as in your face as my Spector Euro 5 used to be.
It's a fabulous thing, very modern sounding, punchy, and weirdly, turned to passive, sounds quite P bass like.
Love it. Total bargain.
