No really, don't do that. As mentioned, it's risky. Also, I'd expect that sort of DIY tampering may void your warranty.
Besides, the pole height doesn't have to match the neck radius. If it did, every manufacturer would design their pickups that way in the first place. But they don't. And every bassist with "flat" poles would be changing their pickups for that reason alone. But they aren't. Good luck.
Yeah, music shop said that it would void the warranty. thinking of going with the warranty option and exchange the bass. Thanks
