Hi Rick:
I used to have a Line 3 and I used a PS Audio P300 with it. It was not a good idea. Sometimes the P300 would cause a fuse to blow in the unit. It caused no damage to the Line 3 beyond the fuse blowing, bit it was mightly frustrating to keep opening the unit up. The problem occured more frequently if I played with the PS Audio multiwave functionality. Overall, it might be prudent to use a more passive type of line conditioner, if at all. Maybe a Walker Velocitor? Good luck.
