you can have pickups that require volts through them to work but you can also have passive pickups used within an active circuit. we would really need to know which pups you have or see the back of the pickups and a shot inside the control cavity.
also, why do you want to go from active to passive?
Also agree. The black wire needs to connect to the largest lug(in the centre between the white and purple) on the output jack.
The schematics for all Warwick basses are available on their website.
I think it may have started as Vester or whatever that cheap brand was that made shoddy looking Warwick copies.
They had the right idea cutting off the head but it should then have either been burned or buried...
I messaged him on Monday:
just so I can be 100% certain, was this bass actually produced by the Fender Custom Shop?
You mention in your listing "Custom Shop" and a "Custom Shop" decal but Im not sure why you are putting these details in quoatation marks?
He replied yesterday:
I’m not too sure if it is. It has the logo on the back of the headstock but no certificate. I put it in quotation marks because I’m not sure.
Make your own mind up about how honest he is...
Ah you see now, it's a Fender "Custom Shop" according to the listing. Definitely not to be confused with a Fender Custom Shop and I am sure the seller has made that perfectly clear so as not to accidentally trick people in to thinking otherwise...🤔
Guys you won't regret buying this bass. That trim pit on the preamp presets the mid range for active mode and it can turn this into very different sounding basses from a very chilled presentation to the most aggressive snarling beast you have ever heard!
I thought the boss had spoken and you are now not going to refinish this one?
Btw, it will be a dye you rub on, not something you will spray on - At least AFAIK
Its a very handsome bass but I am not a fan of this new shape of the Streamer body. the lower horn just looks wrong and the contouring, or rather lack of, on the rest of the body is not an improvement either.
