Default Is there an inexpensive hum cancelling dog ear P90 set for an Epiphone Casino?

The guitar is not worth several hundred dollars of high end PUs. Stacked, side-by-side, or just a reverse wound option for both pickups selected together would do the trick. Several venues we play have such strong electric noise that true single coils are useless.

There are noiseless P90s (or is that the p100...?) but if cheap is preferred you could go a long way by shielding the cavities - my Tele was really noisy when played (or rather when I wasn't touching any of the metal work or strings) and as I understand it a lot of the noise is interference channeled though the player's body. I shielded every cavity and the underside of the scratch plate and made sure that it all on connected (Faraday Cage) and it made a huge difference.

Hum cancelling means humbuckers which are two coil pickups wired out of phase so that they cancel the noise. You cannot do that with a single coil. The best you can do is to shield it real well.

I used P-100's for a long time and they sound good but they get a bad reputation because people think they are just a hum cancelling P-90. They are no such thing. They are humbuckers that fit into a P-90 routing. Because of this a lot of people spliced one of the coils out of the circute to effectively create a single coil pickup. I did it and still they don't sound like a P-90.

As such you can usually find them on e-bay for cheap. I'd be happy to part with mine if you are interested, I would just have to rewire it to a humbucker. I replaced mine with P-90's and I do like the growl of the P-90 better but P-100's are good clean sounding pickups.

The one's I have are original Gibsons. I'm not sure any third party maker has ever copied a 100.

Why not just reverse the polarity on one of the pickups? That way they will act as one humbucker with the switch set for both pickups.

You can do that and it is commonly done but then it will only be hum cancelling in the middle position.

To keep the combined signal in-phase I would have to remove and reverse one pickup's magnets. Not sure that can be easily done.

I'll cast a vote for shielding. Done properly, it is highly effective in taming the annoying hum.

I had a strat style guitar that was just unbearable. At first I thought it had some sort of grounding issue, but then I decided to try shielding. I shielded the cavities, the underside of the pickguard and also stuck some copper tape around the back of the actual pickups. To my complete surprise, there was zero hum. I was blown away.

There are plenty of videos on-line outlining the process, but I just want to mention two things to be aware of:

If you use copper/aluminum tape, make sure that the different pieces are actually making contact. My copper tape had a black non-conductive adhesive on the back. So when I laid out all the different pieces, there was a good chance that none of them had any contact. My solution was to add beads of solder at the boundaries of the tape.

Beware of ground loops. Once I shielded the cavity, I made sure that it only connected to one ground spot on the electronics. That is probably playing it safe, but the last thing I want to do is have to take the entire guitar apart again because somehow I am back at Square One.

Hope that helps. Anyway, let us know what you decide.

The hum-canceling dogears I know of are about $100 apiece or more. These at least are RWRP:

Guitar Fetish dogears

Don't have any experience with these particular PUs but am happy with a Strat set from them.

Good shielding makes a huge diffference, particularly in Strats. Not sure how one would go about shielding a Casino, though. Maybe using shielded wire where possible would help.

Perfect! And I thought I had checked there...

It can be easily done but you also need for that one pickup to be reverse wound relative to the other one.

I'd just order a set of Duncan P90's with one RW/RP (reverse wound/reverse polarity) relative to the other one. It's a standard option.

Then when you combine them you'll be hum free. But only when they're combined. And about $75 each.

Or you could go this route and get some stacks: http://www.musiciansfriend.com/soapb...le-coil-pickup

Probably more than you want to spend though.

You do need reverse polarity but you don't necessarily need reverse wound pickups.

If the coils are wound the same way you'd connect either the two finish wires or the two starts (doesn't matter so long as it's the same one from each coil).

If the coils are wound in different directions you'd connect a start from one coil with a finish from the other.

Provided the magnetic field is opposite in each coil, they'll be humbucking and in phase either way.

Maybe this helps explain it. It's not meant to be a literal drawing of a pickup coil (the magnetic field flows up and down through the coil not across it) it just shows how the three variables combine with respect to hum-cancelling and phase.

Ugh, the horror of P90's. Can't stand the sound of these.

My son passed on a brand new Epiphone 339 in cherry red because of the P90 Plus pickups.

We found a Epiphone 339 ES in Pelham blue with Alnico humbuckers and it sounds so much better.

You think? I dunno about that...

I guess we like the older sounding semi-hollow versus the new ones with P90 or PLUS pick ups. For him he wanted something different then P90. When your looking for the same model guitar place after place and they all sound the same at some point you want to be different.

I have never ever liked a humbucker that was supposed to sound like a single coil. Side by side, stacked, double rail, none sounded like a single coil pickup.

Never got to try Bardens though.

There must be a bunch of P 100s out there cheap if that's what you want.
