Double P bass pickup wiring question.

[CRich0205]

I have nothing to add. But the bass in those videos sounds absolutely killer and now I want one.

I can't certain that switch has 4 pole because of my poor english.
I think it looks like a 2 pole switch. Please tell me if I misunderstood.

So sorry -- I took a look at the document and I believe that you are correct, it is still a 2 pole switch! Good eye!

May try (for the bridge pup) a; MM, MFD-Bucker, Bigman, or Big split in a franken pj i am rebuilding with a custom metal pickguard i have fabricated (still need to cut the nk pup opening into the guard)..
any recommendation(s) appreciated, p

It's a route with lots of possibilities! As I listened to the plan, I remember Billy Sheehan's model. I'm curious about the results.

Are you talking about PB-555? I like the Pbass type sound, but I have never used it on the bridge. I am pleased to hear the sample, so I want to hear the results.



Other sound sample of double p bass. I like every mode of this bass. The bass that i apply to is hollow bodied bass but I expect similar result.

You give me a big inspire to add the 2 pickup series mod. I don't think about it before you mention about it. Thank you so much!

yes, i will be trying different pups (basically using it as a MOD platform), made 2 blank metal pickguards for testing. thanx

I found the 4p6t switches that I bought online and liked quite a lot: https://www.ebay.com/itm/140939259413&frcectupt=true

As you said they might not work well for you because of the shaft length, but I was just so sad that I couldn't find them on eBay anymore that now that I've found them again I feel the need to share it somewhere!

Sorry for the delayed post, but I just checked the schematics and I think that the Free-Way Ultra is an unconventional switch -- it seems like it's 2p6t but each pole seems to sweep through *two* sets of lugs, so that when the switch is in position 4, say, then CA connects with two separate 4A lugs, but when it's out of that position the two 4A lugs don't connect to each other. Anyway I don't think it matters to you but just wanted to clarify in case someone one day searches and finds this thread.

I done it! Decided it!
I decided to solve it this way.

Inspired by what solderfumes said, I decided to add two pickup series modes as well.
I listened to some of the sound samples of some double P-bases, such as the Mockingbird bass, and thought it was a mode with awesome growling.

So I decided to construct with 3P4T rotary switch and push-pull pot as above.
The operation may be a little inconvenient, but unlike guitar, it is wouldn't be matter since there is very little chance to operate the selector during performance.

The rotary switch can select four modes: neck / neck+bridge parallel / bridge / neck+bridge series,
and can use bridge E,A+neck D,G mode by pulling the push-pull pot with rotary switch sets to neck+bridge series.
NeckE,A and Bridges D,G were omitted because they would not be used. So in fact, the number of all cases can be applied!

I wanted to use Bridge E, A and Neck D and G modes because I am missing the sound of Aria Pro 2 CSB-450 model.
csb-450 - Google Search
It's a 32 inch scale set-in neck bass with P-bass styled sound.
But the pick-up position was located slightly backward and the polepiece was also a reverse type, so it has a tight modern sound than the typical P-bass.
But It has just one pick-up, so I've sold it for use different basses, but the sound of it was fit for my taste very well.

I expect the bridge E,A and Neck D,G mode make the sound of CSB-450.

Anyway, thanks for all the advice!

Thanks for this layout, I traced out all the different options.
