I have always wanted to try a humbucker in the neck of my Casino Coupe.

A simple DIY pickup "holder" ( made from orthotic/prosthetic "plastic" sheet material of some sort) , one solder joint, and.... voilà!

No alteration/enlargement needed to be made to the rout.
(N.B. This would not be the case if the humbucker had a cover)

Shorter height adjustment screws were essential. I substituted the height adjustment springs with rubber tubing as the springs were a bit too large for the shorter screws.

My thanks to @laristotle for the pickup and for his ongoing interest in this experiment.

Thanks to @Hamstrung for the thread title.

The next project is to make a decent looking pickup holder...probably from wood.

I would imagine that @Robert1950 and @Scotty will be interested in this thread as they are also Casino Coupe owners.

Sorry about the terrible pics...

I haven't had much time to try it. However, the humbucker seems to have fuller, thicker tone. I need to try it quite a bit more and likely lower (?) the pickup height.

I'd appreciate any suggestions form the woodworkers in the forum.
I have some 1/4" hardwood but I'm wondering if thin plywood would be a better choice. That area of the guitar top is quite flat and there are very few significant forces going through the pickup holder but I am a bit concerned about it splitting along the grain (as shown by white lines)

I have questioned using lexan or copper clad board. I do not want to use metal.

Thanks for your suggestions.

Cheers

Dave

since the beginning of time it has been said that a square peg will not fit into a round hole.
Dave....you have managed to prove them all wrong....congrats.
Now you just have to make it look pretty.

I would make it out of hardwood.... if it does break- then remake it out of ply.

Ideally you would make it out of veneer, 3 layers glued cross grain to each other.
That would be as strong as ply.

Solid wood that thin (I’m assuming thinner than 1/4”) won’t move too much & you will probably be fine.

Thanks Nathan. The wood I have available is just under 1/4" thick.

What did the cavity look like before the humbucker was put in? Was it a standard dog ear p90 rout?
The dog ear P90 rout dimensions for this guitar seem larger than I think is typical. I'm quite sure this pickup is not all that standard. However, I could be totally wrong.@Robert1950 knows more about this as he had his stock Epi Casino Coupe P90 rewound by Vineham (IIRC).
Cut up a dog ear pup cover?
I'm quite sure I read about this in the past. There is very little room in general and I think the adjustment screw holes were an issue.




I really should be spending my time learning to play the guitar and not tearing it apart. This is just too much fun and I am insatiably curious.

Casino Dogear Pickups according to Lollar.........

CASINO:

The Epiphone Casino (also the Wildcat) is a "whole different animal" although it looks a lot like a standard dogear set.

Your first decision is whether or not you want to use the chrome covers. Something to consider is that with plastic covers the pickup will have a little more high end because the metal covers will reduce the top end a little bit. Also, the metal covers have a tendency to feed back microphonically, even if the pickups are potted to an extreme.

If you decide to stay with the chrome covers, you will need to send in the entire unit: cover and chassis. On some versions the lead wire is built with a clip type connector at the end of the lead wire. This connector has two halves: half is attached to the guitar wiring and half is attached to the pickup lead wire. If yours is built with this type of connector, leave the pickup half of the connector attached to the lead wire and send in the entire assembly - pickup, chassis, cover, leadwire with clip. On a Casino set we re-use both the covers and the chassis. We basically "gut" the pickup and build a new p90 into what you send us.

If you want to change to the plastic covers, the process is different. As you know the standard chrome cover/set up on the Casino typically has quite a slant or slope to it, especially on the neck. We prefer the way our replacement pickups fit on the guitar body. They attach to sit parallel to the arched top, and provide a close alignment of the pole pieces and the strings.

For a replacement for Casino neck we use a short neck with a 1/8" shim and an optional 1/32" shim. For a replacement for Casino bridge we use a standard (tall) bridge, no shim.

If you send in your Casino set for re-use of the chrome covers, turnaround time is around a week to 10 days, after we receive them. The re-builds are $210 for a standard set, plus shipping - or $110 for a single pickup. '50's Wind are $250 a set, or $125 for a single pickup.

I would have thought the "natural place for adding a humbucker to that guitar would be the bridge position.

One thing I've wondered about is what a P90 would sound like with one of the magnets removed. A stock P90 has two bar magnets coupled to the centre block, such that the adjustable screws are opposite pole to the edge of the two bar magnets coming out the sides.

I would suggest a different baseplate for the neck HB, but I understand that baseplate material is also important. So unless you could find one that is of similar material, but a bit "leaner", you would be stuck with the opening and setup you have, OR enlarging the opening. BTW, just how much more would that opening have to be to fit an HB with cover?

I never use the bridge pickup.

It would require removing about 1/16" of wood along the side facing/nearest the bridge pickup. That would be fine, except the gap would likely (almost certainly) show if I put it back to the stock P90.
Why do you ask? (just curious...it was my curiosity that got me into this in the first place...LOL)

I asked just to find out if the modification was merely a simple nuisance or something more substantive...which it appears to be.

A concommitant question: are plastic P90 covers a little "wider" than metal? That is, would a plastic dogear pickup cover compensate for the additional 1/16"?

The Gibson equivalent to the Casino Coupe is the ES390. This has been issued with both Dogear P90s and Mini-humbuckers. I have often wondered if a Casino Coupe could be retrofitted with mini-hums. It sounds like the cut in top might be a little big, assuming I have read this correctly.

Much easier than what I'm doing and has been done by a few.
