I just received a stingray 5 I bought as B stock. Long story short- the neck is still bowed and the truss rod is not tightening any further, even with pressure applied pulling back the headstock. The company I got it from is not returning calls, emails, or messages. Assuming I may be stuck with it. Was thinking of trying a string change. Don't like the gauge or feel of the factory strings anyway. I assume a lower tension string would take pressure off the neck and relieve that bow a bit. Is this the case? Could a lower tension set, over time, actually allow the neck to reset a bit and the truss rod to be tightened again?
