Well, took me a couple weeks now that I'm back to work but found the issue. After my disc replacements I've had to wear a bone growth stimulator device. Seems that when it's charging it cycles causing the intermittent interference. I knew I couldn't play with it on as it covers my neck around my shoulders but once plugged in to charge I thought it was off. Not completely, I found. Once fully charged and unplugged, no problems. Bass worked fine across the street, but didn't put two and two together until last week!
As always, love the advice here. Even when I can't reconcile it quickly!
Happy playing everyone!
