Peavey T-60 Super Ferrite specifications

[SpareRibs]

Hello rjb,
Yes I thought of that but a lot more is going on. I am not sure what the previous owner did. The pots were shot.The caps were junk, and it all looked like it was soldered with a blow torch. I set it up like a Gibson with 50's wiring so that is probably a problem too. Chip Todd has stated that all the pickups were the same they just shortened the wires upon assembly. I first set it up with the 500K pots, when I read they were set up with 250K I bridged the pots with 500K resistors
That did not help either. I am going to have to set it up stock and check it out from there.
Anyway I still want to wind the blade pickups, as they are supposed to have more clarity.

Hmm, that was my impression of the stock wiring in my guitar.

Do you mean you used the pickups as straight humbuckers without the coil split?
Taped off the red wire so it doesn't short?

I first set it up with the 500K pots, when I read they were set up with 250K I bridged the pots with 500K resistors.

I haven't tried it yet, but would think they would sound better with 500K pots in humbucker mode.
I think I read somewhere that they used 250K pots to get the split coil sound close to authentic single coil.

Anyway I still want to wind the blade pickups, as they are supposed to have more clarity.

If you have the $, I have a hunch that (the person) Bill Lawrence's "Wilde Bill" L500R pickups might be a good substitute.

I also have a hunch that David Schwab may have some insight on this.

Hello,
Set up in the Gibson 50's style was instant mud. I used the .033 cap on the bridge .022 and a few more combinations to no avail. I think the whole circuit has to be complete as designed to work properly. Chip Todd said taping off the red wire was one modification he did on all the T-60's he owned. I know that maybe an L500R may be a good alternative, but I am takinthis on as creating a duplicate for direct replacement in existing covers.

Also interesting that he considers the T-60 "guitar" pickup a better bass pickup than the T-40 "bass" pickup.

That was the same interview I posted from above. He seems to like a very bright bass tone, as he talks about the overtones a lot. Unless I read it wrong, he also said the guitar and bass pickups were the same, so that confused me.

Hello rjb,
I know bypassing the single coil split is odd but look at the way we modify guitars. If I were in guitar manufacturing I think there would be room for improvement on anything I made, I think there would be a tendency to constantly improve things. Dan Erlewine at Stu Mac is a bad example of that, all of his projects are designed to use the maximum amount of high priced junk on every project he takes on. So it ends up costing $75.00 to change your strings. At least with the Chip Todd mod all it requires is the clipping and taping of one wire.
I am still looking for the amount of windings per coil, its like pulling teeth, But I will find it somewhere.

I strongly disagree with this. Dan knows what he's talking about. At Stew Mac he's showing how to use the stuff they sell. He also helped develop some of those tools. They sell lots of very useful things, and some not so useful over priced things. But if you really look at some of the work he does, he will improvise and make tools from junk. I've actually met the guy, and my friend and former business partner studied with him when he ran the Guitar Hospital.

And you don't need anything better than a "junk" cap in a guitar. That's where you are over charging on parts.

Post 20 is screwy.

The quoted text cites SpareRibs, but is from a post of mine... which has disappeared.

Nee-nee nee-nee, nee-nee nee-nee.

Anyways,

That was the same interview I posted from above. He seems to like a very bright bass tone, as he talks about the overtones a lot. Unless I read it wrong, he also said the guitar and bass pickups were the same, so that confused me.

I think he was saying the guitar and bass blade pickups were the same except for size.
If they both have the same number of turns per coil, but the bass coils are longer, then the bass coils require more wire and have higher resistance per coil.
I think his assertion was that the higher resistance reduces high overtones.

That's weird! That was my post. Maybe I hit edit instead of quote? Are you missing a post? I think I posted that from my iPhone, and that damn screen is kinda small for my eyes...

[rjb]

Are you missing a post?

Yup. I think it was probably the original post #20.
It contained a quote with 3 paragraphs of a Chip Todd interview.
No biggie.

...mine are the ones with two magnets as the guitar is a 1979 model, which would be the weaker ones with less clarity.

I wouldn't be 100% sure of that.
My T-60 has an 8Mxxxxxx serial number; according to the Peavey-related websites, it was probably built in 1978.
I bought it used in 1980, before the exposed blade pickups officially came out.
The pickups look like "toasters" but are constructed like "blades".

If you take the backplate off yours, you might be surprised to find one magnet and two (unplated) steel bars.
Then, if you want to replicate an early official blade PU, you just have to build a skinny bobbin, a plastic faceplate (I vacuum-formed a pair from .02" styrene) and maybe the plastic body/mount.

FWIW, I think the PUs I rewound are plenty bright, even with the brass covers and baseplate.
(I stuck the pickups to the baseplate with double-sided foam tape; maybe eddy current loading is reduced because the BP is a bit further from the coils than in the original assembly? Maybe my amateurishly hand-guided and tensioned coils are a bit underwound and have lower inter-winding capacitance than machine-wound coils?)

To anyone else interested in this niche topic:
SpareRibs went to the "T-60 Mafia" forum and got a lot of good info from the horses' mouths, so to speak.
Chip Todd drew and posted dimensioned assembly diagrams of both the toaster and blade style pickups.

Theses bobbins are almost the same:

Pretty close, but what fun is it to buy ready-made bobbins?

Depends on how many bobbins you have to make! I used to make all my own bobbins, and nothing beats pulling some out of a bag! I still make some of my bobbins.
