I own a Larrivee OM-03RE (about four years old) which includes the LR Baggs Element Notch electronics system.

Recently I've noticed that there is a varying amount of static present in the signal from the guitar. I've swapped out batteries in both the on-board preamp and in my Para DI box as well as cables, and found that the problem remains. (For a true A/B comparison I also used the same signal chain with another guitar. The problem did not appear with that guitar.)

Is this a common problem with the Element Notch system, and what's the best resolution?
