The description in the picture says:
"John Moyer’s pedal board on stage with Adrenaline Mob. An EBS MicroBass II deliver a clean tone processed by the preamp to one of his heads, and the EBS MetalDrive adds a slight distortion to his other rig, kicked in on the solos."
This preamp is just great! It's great for live situation (especially when you have two instruments). It's great for recording - I quit using bass cabs in studio, because this thing's speaker sim is doing a great job.
