I’m pretty sure my bass bar is loose... again. Same symptoms as last time, Bass rattles with no open seams, and stops when pressure is applied to the top right at the bass bar, and nowhere else. This happened last year around this time, and the solution was to have a new bass bar made. This was done. Now we’re on bass bar #2. Now that this seems to have happened again, I have to ask... How common is this ??
