Variation on SD Spin-a-Split

[Cenulab]

Hi nuts,

I've been trying to come up with a way to sculpt the characteristics of my bridge HB for a while, and I came up with this...

I posted this on the SD website, and Artie was nice enough to do a diagram and analysis of this circuit.

Anyway, I was just wondering if any of you nuts had tried anything like this. I've found it to be very useful, and you can't beat the price! ;D

I used to do something similar with Hot Rails pickups. I left the red and white wires together, and they went to the middle lug of the pot. The end of the cap that you have grounded went wherever the pickup's black wire went. I also used a .01uF cap. I ended up replacing the pot with a switch, since it seemed to be pretty much an either/or kinda thing, with no subtle variations in between.

This circuit is very tweakable, but for simplified live applications I could see wiring up a switch with fixed resistors to get a "full HB / tweaked / full split" set up...though I really like being able to dial in the right amount of "sting", particularly when combining the BR and Mid in parallel.

Hi Cenulab!

thanks for bringing this mod to attention, never heard of it before. i was wondering whether you thought this to be and improvement to (a better idea than) bringing to the tone control to the bridge as far as controlling the sound of the humbucker is concerned?

I'm about to wire a lil 59 in my bridge and wouldn't go without dedicated tone control, but it looks more interesting to have coilsplit and tone control.

Hi Zjokka,

It all depends on what you're looking for...

This is a circuit that I "dreamed up" (through the influence of this and other forums) because I felt that my standard humbucker wasn't giving me ENOUGH treble, so it basically has (almost) the opposite effect of a standard tone control. I currently have my guitar wired with a master tone control (.015mf) which interacts quite effectively with the spin-a-something. I understand where you're coming from, though; if I had more room, I'd do a dedicated tone control in conjunction with the spin-a-something.

I suppose one could use concentric pots...

Another option would be to use the half-split sound as your "standard" and when you want more bass, roll it over toward the humbucking end of the spectrum (which is a technique that I've been experimenting with lately...happily, for the most part.)

So again, it depends on what you're looking for...
