Trying to decide on a pickguard for my P Bass

None pickguard is best pickguard.

 

Not a P bass but you can see how nice transparent brown works with natural finishes on Bacchus basses, allowing the grain to show through.

Other than that, here are some colors you don't see too often, some of which would look great on natural finishes.

 

I've taken the pick guard off my 4 string P bass, but I prefer the original Tort. As I don't play it these days I'm not doing any more work on it. I don't have pics. I also have Tort on my 5 string P bass and my Jazz. I know I'm old fashioned, just looks right to me.

 

That's cool … I haven't been able to find them … source?

Ash & maple needs a black guard. Pure class.

 

I'm a big fan of the naughty but nice pick guards from greasy grove.

Does anyone here rock one of these? What a gas!

 

Oxidized bronze I think would look good on a natural oil finished wood body, perhaps an oxidized iron pickguard would look even better actually.

A wood pickguard in a bit darker or lighter shade than the body of your bass would also be a good looking solution, perhaps one of really dark, almost black, wood, like ebony, even.

Whatever you do don't put a tortoise pickguard on.

Personally I'd probably go with the oxidized iron or the ebony pickguard, if ebony perhaps one with some of those lighter stripes ebony sometimes got in it.

 

I would say with natural ash body and maple neck, I would suggest Tort. If it were a rosewood fretboard, I would suggest a black pickguard.

 

Tortoise (IMHO)
