No band sounds better than its bass player. Bass is the linchpin between rhythm and melody...a big responsibility. 

The essential ingredients of great bass tone are Pitch, Punch and Power.  Pitch, so the frequency of the note is identifiable and accurate...not the flubby rumble often heard. Punch, so the attack of each note is a precise event in time.  And Power to deliver these two with authority and headroom ...and to disembowel the first 5 rows.
