Despite this truth us bass players still have our playing preferences. The audience indeed couldn't care less either way. Maybe the OP can try your suggestion with his Warwick as it has a MM style humbucking bridge pickup.
I've had one,fine bass. If you're after a 5 string P bass with the same spacing (16.5mm) that might not happen unless you commission a build. My previous suggestion is all I have at the moment.
What model of Warwick do you own and does it have a preamp bypass option? I'm thinking you could try using it neck only and bypassing the preamp.That might get you close enough?
I mentioned this on my list posted a while back. I have a Fender Jazz that came with one and I bought it KNOWING the stock white pickguard wasn't going to last long on it. I just can't stand them 🤭
I now find 4 strings weird.I skip over them in the classified ads for sale like you wouldn't believe. In fact I wish could filter them out of the search listings 😄
Once I realised that a 120 B string has no less fundamental than a 130 I now exclusively use 40-120 string sets. This is only in my experience I should add.
The highest number I ever got to was a pitiful 5 😄
