Hey guys, Im finally getting round to making my Filter'tron frankenstrat
Ive got an old, fake strat (a highly useful base for a frankenstrat) a Gretsch filtertron pickup, And im going to go and pick up a few lengths of wire (to make it 4 conductor) a couple of Push/pull pots, and hopefully can figure out what to do with the pickugard
A few picks with the pics with the pup mounted
Im going to my local music shop to see if i can get soem parts for the trem ( its missing a few screws) as well as whatever i said up there. (P/P pots, switches, strings) and then i cna have fun trying to find the jack plate cover =.=
If you had a single humbucker, and just three switches for it, what options would you have? im thinking series/parallel and a coil tap. But I dont know about the last one?
Spin-A-Split control to achieve a 'variable coil tap,' and wire the two together.
so for the variable coil tap, do you just put a pot between the Pup wire, and the ground, so that you can adjust how much signal from one pup you get?
As a note, The axesrus brand pickups are made by the same people that make most GFS pickups, Artec Sounds, so if you are struggling to get GFS in the UK, you should get some very similar pups there. (some models look REALLY similar to irongear pups too, im looking into that)
Im gonna pop down to my local shop and see if they can order some kit in for me. the delivery system at my flat is stuuuuuuupidd
I've used the Seymour Duncan colours for the humbucker wires in the diagram. If you wire it like shown, with two DPDTs, the right-most switch changes the pickup between series and parallel, and the leftmost switch (with the attached pot shown above it on the diagram) turns on the variable coil tap. If you're in series mode, it varies how much signal goes to ground from the series wire, and if you're in parallel mode, it acts as a separate volume control for the South pickup (red and green wires). So essentially, it's a variable coil tap that works regardless of whether your pickup is in series or parallel.
This is all in theory. I haven't built this yet. But so far nobody sees any reason why it shouldn't work.
I like my "spin-select" control on my new strat...
spin in the HB, pulling the control selects which coil you are spinning out of...
However, this pickup might not sound that great split or be that different between splits.
The 'frankenstrat' thing though tends to be more about making something that works and adaptable and this guitar looks more suitable for this.
Perhaps it would be 'better' to leave off a pickguard completely, add some foam (cut up a sponge if on a pinch) and put it under the pickup for 'springing and use some smaller screws or a bracket to mount the pickup directly to the wood from above.
This allows you to have a guitar that you can test all kinds of wiring ideas on.
For the bridge...it's looking a little old and cheap...on my messing with such guitars in the past I used suitable cheap replacement bridges...watch the string spread as most cheap strats have narrower bridges and necks.
This is my 'test guitar'..the 'pickguard' is a bit of plywood. I actually use decently strong but cheap foam backed double sided tape to 'stick' pickups anywhere in it's bath tub route. The pickups are screwed to bits of ply that are adjusted with stacked up foam tape here.
But if you wanted to go a more EVH frankenstrat kind of way...follow his example perhaps. You never know when you might come across another pickup you want to test or some crazy wiring idea that you could use such a guitar to test it out on.

Good, news, I have to go ahead to spend a little money on this guitar now two words come to mind. Broard Bucker. Would it be possible to make one of these with two P90's? run two p90's in a telecaster wiring, with a broardbucker switch?
Borsanova's original Broadbucker idea was a tone pot in between the series connection; the switch idea replaces the pot with a fixed cap.
Yew, if you're digging the broadbucker idea, and you like the series/parallel option between two coils, be them two coils of a humbucker or two P90s, I think you'd like to see this.
That's the Series/Parallel Spin-A-Split control, but instead of just swapping between 'On' and 'Off' there's a few more options. In Series mode, the Spin-A-Split swaps between a Tone control and a Volume control for the South coil/pickup. When the pot acts as a Tone control, that's Broadbucker mode. In Parallel mode, the Spin-A-Split swaps between a Master Tone control and a Volume control for the South coil/pickup.
Thanks for the help guys, im trying to find a way of changing between the parallel connection of a tele switch, to a series broardbucker config, however i cant work out how to do it with as few switches as possible. maybe i could use a strat 5 way switch somehow, to allow me Neck, bridge, series, parallel, broardbucker? but i think that would need too much cleverness for me to have
Actually, Ive just thought that it could be possible, i have to get to a lecture, but i might have had a brilliant idea, ill take a sketchpad
Nope, my brilliant idea never happened. However Ive been thinking, would 2 p90's actually sound good in a broardbucker ( bridge and neck) if anything it seems to me that I would have to find away of cutting some of the lowest bass out of the neck
That'll work. The cap could just as easily go between the two top lugs and accomplish the same thing. Values for these are generally in the range of standard tone caps, but experimentation is the best way to learn.
Thanks ash , Im thinking a 0.22 cap, as the pot should be able to reduce that value to sound similar to a 0.47 if needed (not quite, but not too far)
I didnt realise the cap could go between the lugs, and that you could do it with a SPDT switch, but I was concerned with accidentally shorting out the guitar with the coil tap switch... and you have DPDT's on P/P pots anyway
Then Im just thinking a standard volume/tone control, and I have 2 500k pots laying around, and can get a Push pull.
I think Ill have the 'fader' on one pot, and the Push/pull on another though, seems more ergonomic to me..
Yep, that will work. I didn't realize you were going to use 2 switches.
One DPDT On-On-On switch (i.e., 3 position switch) can give you series/parallel/coil cut. If you use 2 switches, you could use the binary tree scheme to cut either coil. As shown, this will work with SPDT switches (On-On):
(Second time today I've had occasion to post that!)
Thanks Newey, although that diagram looks far too complicated for me, but is probably what is in SD's tripleshot thingy
Can you think of any way to vary the amount of coil tap? maybe using a pot to become a potential divider? putting some of the current to ground, with the rest going back into the circuit? I suppose that could work in series, but I dont think it would in parallel. But then again, you couldnt have a parallel broardbucker and a coil tap wouldnt be that useful....
sorry thats really unstructured, im thinking about it... and also thinking of getting some lunch....
Or what about an inverse broardbucker, with the highs in series, and the lows in parallel... could be a good sound...... wait, that wouldnt work, why would the highs go through the second coils resistance, when they could just go to the hot? Although....... maybe a 500k pot could make going through the coil easier for the highs than going through the pot. now to work out a way to do it on one dpdt switch
If I Put a pot that links the 'earth' on my above diagram to the black wire on my coil tap/broardbucker diagram, then that would act as a standard coil tap/broardbucker in series, and could give me more highs in parallel (to top end of the coil would be in parallel, and the low end hanging disconnected.
To reiterate. That's a series/parallel switch and a tone control/variable coil tap switch. In series mode, the tone control works on the series link between the North and South coils, to get a variable broadbucker control. In parallel mode, it's a universal tone control. The variable coil tap works the same in both series and parallel mode.
If you want series/parallel/variable coil tap with a separate tone control that's always on for just one coil, that's just a quick mutation of the first scheme. You're working it out yourself, so if you don't want to spoil the answer I'll post it as a link.
A link. (I think. This one is not as vetted yet, so better not to hedge a bet.)
