Say we plug an ordinary old Fender Standard Jazz bass into a an ART ProChannel (I or II or whatever) preamp into a Crown XLS series amp into (say an Aguilar or Ampeg or what have you) cab. How much actual character is present in the tone? Is it stale to just plug a regular preamp or channel strip into a PA or is that inherently an amplifier rig? Simply, Would using a channel strip or average preamp (with no 'character') into a PA into a cab be sufficient for tone? Is a regular amp setup inherently just a pre/PA/cab?
