Musicman 5 string bass @shroprockdoctor for investigation of a fault reported to be a suspected issue with the pickup.
As with all active electronic loaded instruments in for work I immediately put in new
This I did & can’t find an issue with any settings selected via the controls.
Replacing the 2014 dated battery that was initially installed still didn’t reveal any problem although the battery was was under voltage when tested, measuring 8.9v so does require replacing.
The instrument was not brought in by its owner so maybe a further discussion is required. I personally feel that the 7 year old battery is most likely root cause.
