I've been using the RSII that came with my Upton Hybrid last fall with good results, but lately it's been distorting on the E string. Eric installed it in the bridge, so I doubt it's a problem with the fit. I'm running it direct into a GK MB150s that sounds just fine with the slab, so it's not the amp.
Also, it just started doing this recently.
Anybody else had this experience?
