Holy shit.... it's a little expensive for me... I have a bass very similar to yours, tyr but with only 4 chords... it's a hand made bass by a local luthier and fretless too... but your bass is simply awesome!!!!!
maybe in a couple of years i can get it like that =P
And BTW, your bass work is one of the best of entire metal scene, I can compare with you only to Steve Di Giorgio and Sean Malone (from metal bass players)... your work on Empiricism and Origin is fantastic... you'd inspired me a lot!
