Blend pot with push-pull?

You'd need 2 pots and a switch on one, they exist but are hard to find. If you can't find one premade, there are places that will custom build for you (I've used banzai.de successfully, not cheap, but not that bad either).

 

Best Bass Gear used to have a few weird/rare pots on their website. I think they had push/pull blends for a while, although I don't recall what taper.

 

You might be talking about this thread:
Coil tap switch for SR 705
But there is no link to a source there.

 

i think warwicks use those; MEC i wanna say?

 

Sorry I can't help you with a link. [email protected] posted this picture on the Ibanez SR forum in response to my question about what switch I could use for coil splitting. He only described it as a 250K Balancer pot with the DPDT push pull lugs. I asked him today if he had any information on where I might find one. If he gives me any information, I will pass it along here.

 

This is the link from Bill @Ibanez.....* WD Music Products - BOURNS® DUAL GANG PUSH/PULL POT WITH DPDT MINISWITCH AUDIO TAPER 6MM SOLID SHAFT 250K

 

Hey sorry for the dead thread ressurect, but @RobbieK, could you describe how to do this mod in more detail? I find myself needing a dpdt push-pull dual gang blend pot...

 

I just sent an email off to Banzai music to see if they'll build me some custom 500K DPDT blend pots. If they say "yes", is anyone else interested? Ordering more brings price per down, and they're starting around $54 Euros, so more would be better.

Any interest?



Low-profile, too, which is great for limited depth control cavities! Most DPDT add-ons put the switch on long ways, this is side ways...

 

I usually prefer active blends or switches, but maaaaaaaybe….

How long is that threaded section? The photo looks like maybe 6mm/0.25”, which is too short for a rear-route setup.

 

I will ask about that - surely if they're doing customs anyway, they can do longer shafts? I hope, I hope. Will email.

 

I see they have another interesting possibility, too - their multi-function pot has 3 resistors, set up as stereo on the inner concentric and mono on the outer ring. So if they would to the top 2 in MN taper and the bottom in regular Audio, then it'd be perfect for stacked Blend and Volume, freeing up a pot hole, might be very useful too.

 

I heard back from Banzai, it's a no go, they can't do MN taper nor do they have longer threaded housings. Well Darn.

 

File under “Doesn’t hurt to ask…”.

 

OK, Plan B. I'm going to try to MacGuyver / Frankenstein something up taking the shell of one and the guts of the other:
Bourns Blend/Balance Pot Mini With Center Detent 6mm Solid Shaft, 500K Mn Taper | eBay
Bourns Dual Gang Push/Pull Pot With DPDT Miniswitch Taper, Metric Shaft, 500K 820454113404 | eBay
Wish me luck. Still leaves the threaded shaft length issue even if it works.

 

Advice from anyone who has successfully done this kind of "resistive element swap" would be more than welcome! I'm hoping since they're both Bourne and the same form factor, it'll merely be disassembly, swapping wafers, and reassembly. Fingers crossed. Especially for my shaky old hands being steady enough lol.
