I always take a DI off a bass guitar when recording or doing live sound. If the player's rig sounds good I will mic it as well. It's nice to have the option of blending the dirt from the miked speaker with the absolute clean clarity and unrestricted bottom end from a DI signal. Fender jazz basses....never a problem to make sound good. Fender P basses can sometimes be a bit tubby but still it's a very familiar sound to our ears. Mahogany body basses like some of the Gibsons however....MUD! So thick and muddy and boomy....rarely have good luck making them sound good.
