OK, here’s a strange question: I have this bass, the very first Quantum. I was going to take it to a gig tonight and let someone play it. You know, that sort of thing that happens these days. But, it’s old and crackles, and makes noises. I have half a mind to rip the guts out and just put something fresh in. But, this is what they call a historic bass. What should I do? Should I leave the original poopie in there, try to fix it, put new stuff in, put all the old stuff in a bag that will follow it around?View attachment 5034612
is there anyone up in the city you trust that knows electronics up and down? gary brawer, perhaps? don't know if geoff luttrell over at sf guitarworks has a dedicated person who can work their magic here. are they bartolini's? yes, a bass is but a tool but anytime we're talking about #1 of anything, it becomes much, much more. :) :thumbsup:

Strip and rip the guts, cleanly, give it to someone to check it and make it work.

Meanwhile add something clean that WORKS in a way you're confident to bring it and PLAY it, basses have no place in museums

Absolutely agree. Even to the point of finding as close as you can the original designers and techs from that era. Or someone qualified to spec out any original components. Anything that's installed replacing the original circuitry is going to make the bass sound maybe completely different and create a black hole destroying the universe. Or at least a very important piece of history.
 
I have this bass, the very first Quantum.

I tend to be neither sentimental nor a cork-sniffing "vintage" instrument aficianado, but even I recognize that someone somewhere -- in fact, lots of someones somewheres, no doubt -- would think that altering the very first Quantum would be sacrilege. Try to keep it as original as possible...so that, worst case, in 30+ years when you're suddenly in need of an emergency medical procedure and in dire need of astronomical amounts of cash immediately, you can sell the very first Quantum to one of those someones.

I'm only half kidding :)

Is that the red narra 6-string with the three Bartolini pickups?
 
Is the noise that bad? Do you think you could hose the pots and hit the connections with a meter, or are you going to need a young priest and an old priest?
It just wasn’t something I wanted to risk rushing into a gig. I already got to the point of getting rid of the noise if I touched the pots a certain way. All good things in all good time!

Maybe a grounding issue? If so, that should be able to be fixed without gutting the bass.

But, my approach has always been to pull things apart and try new stuff. My profile photo probably gives it away. My early 80s 6 string Modulus has been through all kinds of mods and I'm not happy yet.
