I'm in the market for an onboard preamp for one of my Jazz Basses; How many of you Bassist feel that a mid(s) control is necessary on a Jazz Bass preamp since a passive J Bass doesn't have and never has had a mid control? BTW, this particular Bass is an Ash body w/a Maple neck and plenty of "natural" mids and top end. I just wanna hear how other Bassist feel about this 'cause I'm kinda feeling a mid control on this particular Bass could quite possibly be overkill and a waste of space on the Jazz plate. Just curious, Thanks. Oh, in this case we're talking about Bartolini (9CBJD1) pickups and ?Bartolini preamp.
