Ugh - sorry to bug but having another issue on the PB2. Before I contact Peter, I thought I’d try you since you’ve been so helpful.
After some use, I now realize I barely get any volume from a Gongue and an Ultrasound (both towards the top of the instrument; the ones on the bottom end work fine). I am thinking it must be something that’s not making contact. Already went through a ton of contacts and put some more solder, but this issue remains. Any ideas what this could be? It’s affecting two modules so I wonder if it’s power related.
