“Cloud Nine”-hot humbucker

 

“Cloud Nine”-hot humbucker

The “Cloud Nine”-hot humbucker is a versatile ROCK pickup with plenty of mids, plenty of power but with enough clarity to help you stand out in the mix.

I am at heart a man of ROCK.

Since the advent of the DiMarzio Super Distortion players have been able to get some power out of their pickups, enough to really push an amp.

The neck pickup needed to be clear and present but with enough power for some of those sweet lead lines. I wanted the bridge pickup to have power to scream with the best of them while retaining enough clarity to have definition. When I play a 7th chord I want to hear it as a 7th and not sound mushy like a John Deere tractor at full throttle. It’s a real danger with hot pickups that they lose character and tone. I needed a crunchy rhythm with strong mids and an over the top lead sound. I want to get squawking pinched harmonics whenever I please. Not only that but I need it it to clean up nicely and react well to a treble bleed circuit. A humbucker for every situation, for players not afraid of a bit of gain.

Not much to ask, eh!

I got through a lot of wire and magnets experimenting over the years to get this set right. I suppose I worked on it for about 5 years, different magnets, winds, wire thickness, insulation, winds per layer – there are a lot of factors. Whenever I felt I was close I used them at a gig to hear how they sat in the band. Pickups can sound quite different next to a drummer or in a mix. I tweaked and adjusted…

Eventually I was happy with the design and I was lucky enough to have legendary Kiwi band ‘Head Like A Hole’ help out with road testing. I knew if they came back from tour happy then I was on to a winner. They did.

When you get it right it feels so good, a sensitive pickup rich in harmonics is so much fun so I called it the “Cloud Nine” which how I felt at the end of it all.

This is the pickup set I gig with myself in my covers band now. I have them in an Epiphone Sheraton with treble bleeds on the volume pots. With this set up it works for everything from The Smiths to Metallica and all points in between. I don’t feel the need to swap guitar – these pickups work for everything.

Here are some sound samples recorded clean through a Fender Princeton Reverb-Amp. The overdrive sounds are using an Electroharmonix Soul Food. The guitar is a ’98 Les Paul Std with D’Addario 10-52’s. All of them with the same guitar, same amp, same settings, no reverb or eq added later.

Fender Lead I Pickup

 I’ve been repairing a few pickups recently and I thought I’d share this one with you. It’s a Fender Lead I Pickup that was sent to me by guitar repairer Jeff Baker from Oamaru.

The Fender Lead I was one of those obscure models that never really caught on and the pickup reflects that. It’s a little unusual and that’s what makes it interesting.

It even looks different with those square topped bobbins.

Not only is it unusual looking from the top but turn it over and it shows what it’s really all about. Those are 12 big adjustable poles screwed into substantial steel blocks and coupled to a powerful ceramic magnet.

This is clearly not a typical Fender pickup, this was designed to ROCK.

It came to me because it wasn’t working and typically one coil was showing ‘open circuit’ on the test meter. In these cases I can use the good coil as a reference to what the faulty coil should be. It had a dc resistance of 7.61 KOhms. Wiki told me the final dc resistance of the whole pickup is approx. 13KOhms so that gave me a pretty good indication of how I should wind it. That’s a powerful set of coils to go with that magnet.

A bit of maths, plenty of experience and some intuition and I had a plan for winding it. Detailed information just isn’t available for this kind of job.

I stripped the bobbin and wound the coil.

I potted it very lightly because these bobbins are made of butyrate that has a lower melting point than most modern ABS bobbins – I didn’t want it to deform with the heat, I wasn’t going to be able to get another bobbin.

Here you can see the chunky pole pieces, they’ll guide a fair bit of that ceramic magnet’s strength up to the strings.

Hofner Pickup re-wind

I had a visit from Paul Crowther the other day (always a pleasure to see him). He's rather a legend for amongst other things his 'Hotcake' overdrive pedals and the 'Prunes and Custard' (my favorite for theremin).

http://en.wikipedia.org/wiki/Emlyn_Crowther

 He wanted to know if my coil winding machine was up and running -  he had an interesting pickup for me to wind.

 Its an old Hofner pickup which I guess is from the 50's. The guitar has 3 of them and this one has a break in the windings so needs to be re-wound.
This would normally be a straight forward job except for the design of this pickup.

 This is the inside of it. The windings (around the outside) are not wrapped around a bobbin. They are just sitting in the pickup and have been wrapped in tape to protect them. In the middle you can see the magnets sitting in a hard putty. There are incidentally only 5 magnets.
 So the problem Paul left me with was how to wrap about 5000 turns of extremely thin wire into a coil and therefore make a pickup.
 After a long brainstorming session with Sheena we came up with a plan.

 We figured that the wire had to be wound around a bobbin and then somehow the bobbin removed.

 So I made this bobbin. The sides are plastic from a Strat pickguard (white) and the centre has been carved from candle wax.

The bobbin bolts together and is attached to another plastic plate which in turn fits to the winding machine.
 The idea is to wind the pickup on this and then warm the completed coil up and melt the wax. The wax should seep into the coil thus potting it as well. Then the sides can be unbolted and voila a copy of the original coil.

 Winding the coil wasn't any different from any other pickup - so now for the tricky bit.

 I warm the coil ever so gently with a heat gun. I put my free hand next to the work to judge the temperature - if it gets too hot the plastic will melt and I'll be starting again.

 When I see some wax oozing out I ever so gently remove the top plate.

 With the wax exposed I can apply more heat and watch it flow into the coil and as it cools becomes solid.

Then I wrap tape around it to hold everything in place. I cannot emphasize enough how fiddly this is. There are a few stray wires and if any of them break I'm starting again.

It may not be much to look at but its taken hours. The slight curve is to match the shape of the pickup casing. I've tested it and I'm pleased with it at 5.5Kohms.
 In the background you can see the magnetic lugs - I had to dig them out of the putty.

 I put the whole thing back together using 'friendly plastic' instead of putty then fill the casing with wax, solder the back on and its finished.

 Its been quite a task but I'm happy with the result.
