Hello. Protest The Hero is fast becoming my favorite band and Arif Mirabdolbaghi is fast becoming my favorite bassist. (though i can't possibly play any of his riffs!) I'm curious though, on Kezia he always played a 4-string Spector and on Fortress he started using a green 5-string Spector. I've looked up tabs (don't criticize me! I can read bass clef!) and noted every song was only a half step down, (unbelievible for a band that heavy) even on Fortress and i'm curious about his shift to 5-strings. I'm aware it isnt just for the low notes but also for position, but im curious for his reason behind his use of 5-strings. Thankyou for your time.
