I figure anything mounted on a piece of wood with electricity passing through it to be the electronics. :cool:

I don't know about your guitars, but on mine there's no electricity passing through the switch cap and knobs. :shock:

Since I'm just now in the process of trying to put my Tokai electronics into my '92 Epi LP Standard I can assure you, full sized pots don't fit. :rolleyes:
The Volume pots fit fine but there isn't enough room for the tone pots in the cavity.

They fit fine in my Epiphone! :hmm: Although, mine never had mini pots.

Take a picture and let me have a look?

I have a MIK Epi LP Burst. Bought it new in 89. Loved the thing and it has always played well. Just never been too happy with the electronics. The toggle switch cap and the two volume knobs all broke and spun off, the first week I gigged with it.

I now have a couple Gibson LPs and thought it would be a good time to upgrade the Epi electronics. I know the pots are metric and the holes have to be increased for CTS pots. Was thinking about an upgrade kit from RS Guitarworks.

The Epi pots are very small in size. After looking inside the control cavity of the Epi compared to the Gibsons, I am a little concerned whether CTS pots will fit correctly in the cavity.

Does anyone know of any unforeseen issues when putting CTS pots in an Epi LP?
Are CTS pots the same size as the stock Gibson pots?

Gibson R7 Cavity:

Epiphone LP Cavity:

As you can see, the neck pickup tone pot looks like it is almost touching the side of the cavity.

Those are not original Epi pots. Epis do not normally come with mini pots.

Actually my 95 MIK Sheraton had and still has mini pots. Unfortunately a full sized harness from RS is like $180 for me so thats out of the question right now.

They are original. My '92 Samick made Epi had the same until today....
and now I can't get the full sized pots in.
My '94 Samick SG copy also has mini pots.

Here you go.

BTW, finally got the harness into my Tokai, together with the Gibson '57 Classic Plus (bridge) and SD Alnico II Pro (neck), and it sounds friggin' sweet! :thumb:

Damn, that's a bummer. My only suggestion would be to get some extremely course sand paper and go at it - depending on how much space you need - it might not be doable.

Great! I'm so glad you're pleased. :D I trust you see what I'm shouting on about when I say an electronics change makes a huge difference? Don't suppose you have a nice control cavity picture with the new harness in your Tokai I could put up on the website?

If you choose to order again remind me to throw in a few extra caps and what not.

Well, that really sucks. My Saien has minis, but that was to be expected.

The newer model epiphones have Alpha pots, my 2000 LP Deluxe, my 2008 SG400, and my 2009 Custom have alpha pots...all full sized. After changing the pickups and rewiring, the pots taper smoothly and the guitars soung great.

I bought this Epi brand new from a licensed Gibson dealer Retail music store in 1990 and has been in my possession ever since. The first time the cavity cover was ever removed was about a week ago to take that photo.

As far as I can dig from the serial number it was made in Korea in November of 1989.

Shifty, I had thought of maybe putting a sanding wheel or a grinding wheel on a dremel tool and just hollowing out a small cavity right where the pot should fit.

Its almost like they just eyeball the pot holes before they drill them.

My 92 Epi Les Paul's innards look just like the OP'S. The early MIK-Samick made Epi Pauls have mini-pots. I need to get around to upgrading some things with my Epi,and electronically, I've got all original parts, including the mini-pots, green Chicklet gum caps, etc, to deal with, besides deciding which flavor of PAF bucker type goodness I want. It looks like the Epi Les Pauls need their own history book put together, to show the changes and specs that have gone on over the years with the line. If I want full size pots, I have the same issue to deal with that the OP has commented on, along with others here.

Yes, I thought about that, too.
I think I'll give it a try when I find the time. :hmm:

It definitely made a difference.
I just made the mistake of changing too much at once (going from the stock modern wiring to your 50s wiring harness, changing the pickups and trying out Elixir Nanoweb strings for the first time) to really determine what change attributes to what.
I was planning on upgrading the Tokai for quite a while.
I bought the SD Alnico II Pro in July of last year to put it in the Tokai, but then I decided not to spend any more money on it before I didn't have a job, again.
The Gibson '57 Classic Plus was in my Samick SG copy since 1997, I think.
When I finally had everything together I was too impatient to do a step by step swap. :D
Ah well, I'll take it slower with my Tokai Custom.

So, here's what it looks like with the new pickups and Gibson gold top hat knobs.

I also took a picture of the control cavity for you.
It's been about seven years since I soldered the last time, but I think it didn't turn out too bad. :hmm:

I was going to suggest a Dremel. Seems like it would be the easiest way and you would have good control of how much material you're removing.

Nothing wrong with that soldering job Shifty.
