I chose a bass while it was under construction from a well known luthier. Spanish Cedar body, Ebony Fret bd, & Madrone top. Very beautiful. I have two similar basses from him. When I received it almost five years ago something was not right. It played well but sounded timid and had reduced output. He graciously had me return it and installed at no charge an upgraded preamp that had mid controls. Their belief was that that would allow a boost or cut in this area and be the fix.
It was partially effective. Meanwhile my other two basses were roaring, tearing up venues everywhere.
I changed strings from the stock D'Addarios to DR Sunbeams. Huge difference on this bass. I love the D'Addarios on one of the other basses.
Still this issue.
Changed to CB Bartolinis. Opened the sound up yet again.
Still this nagging issue. It was tired on a kicking gig. Reduced volume of about a third compared my others. Excellent in the studio.
The Luthier was partially correct in saying that the effects of the wood choices could be to blame. Making a compressed deep sound without much liveliness. I would just get hiss if I turned up the treble.
I was about to sell it. I had resigned myself to studio use only. Then....
I took it to my tech who Sadowski speaks highly of by the way. He asked the same questions about the woods. He asked how does it sound acoustically. I told him I'd been through all that but that the volume was only two thirds of my other two and about the no highs.
He placed it on his jig. He opened the back plate looked around then said, "hmmm".
He removed the jack and said, "hey did I see how tight that was?"
Drum roll please.......
The positive post was touching the shielding!!!!
Voltmeter confirmed suspicions. He said it would be like having a master volume turned down. I'd have reduced frequency response. Now insulated and isolated. Voilá!
It's unbelievable. Turns out that all the new ones have shrink tubing there to prevent this but mine was done when an "inconsistent" employee was on staff.

Anyway, it's a Monster! The mids are huge. It's like Xmas in that I just got a new bass whose characteristics I'm just beginning to explore.
So hang in there.
