Thanks for the information! Welcome to the forum!
+1 and yes...Welcome.
Good info. The subject comes up around here frequently.
Seems that all the 90's Sheratons out of Korea were that way. Plenty of threads on how to
get around it....but....
I've never seen anyone post that they found one that was a direct fit.
Welcome aboard,
Willy

Good info guys.
This one is going in my list on page 4 of A.F.'s DIY.

Rednefceleb,
Blueman335 made some interesting comments here:
He seems to have a fair handle on magnet types. Maybe he will chime in.

I found the problem. Everything is in working order now. It was a grounding issue.
To tell the truth, I figured you'd get it figured out.
Did the volume tapers work out the way you wanted them to?
Next time someone wants to do a 50's upgrade it will be your turn to do the explaining.
Big time CONGRATS!!!

Pics?
If all the wires seem to check out for correct location (especially at the switch) then something should work. Even if you did burn out something, the odds of burning out everything are small.
Any chance you forgot to solder the third leg of the volume pots to the back of the pots?
Are the backs of the pots all grounded together?
Any chance that the caps are touching the walls of the cavity and grounding out?
No chance you got the power and the ground wires reversed at the switch?
Willy

It won't make a sound at all.
Zero, Zip, Nada, Nothing? In all three switch positions?
Naturally, pics would help, but.... If you are positive that all is good up to the guitar...(no bad cable...etc.)
A couple things come to mind.
If there is a switch problem it is likely a mixing up of the wires at said switch. (or the ground or hot wire contacting a spot it should not)
ALSO...as simple and silly as it sounds, I've accidentally reversed the wires at the jack before.
If you went with vintage wires, it can also be easy to get them mixed up. I like to use marked pieces of tape to
keep track of them until I am ready to solder.
If it helps any, take a quick look at the pics I posted here:
http://forum.gibson.com/index.php?/topic/82973-lp-redo/page__view__findpost__p__1145594
Just don't get too frustrated...(and don't throw it out the window)
There just isn't that much electronics inside a guitar. You'll get it figured out.

I love my Gibson but......I also love my Epiphones.
My only regret is that if I buy any more (and there are a few others I would like) my wife will disown me.
Now I'm thinking and smiling.

I have dealt with braided wire before, but I didn't know what I was doing then (not that I do now
![[lol]](//content.invisioncic.com/p286412/emoticons/default_msp_lol.gif)
). I've read some of your stuff WW about it, and I believe I have seen pics also, but help is always appreciated. This is the video I was referring to:
Small side thought...Set your pots to 0 when soldering. If you accidentally overheat you can create a dead spot.
(Fairly rare but, it can happen) If it does then you want the dead spot to be at 0.
The only other thing I was going to show is an easy way for stranding the ground when desired....A toothpick!
....
This was part of some tests I was running. The finished wire was (of course) much shorter.

TBM,
Looks like you're making progress. Thanks for keeping us updated.
Just a couple of questions.
I see you have four capacitors. Planning on doing some experimenting?
You may find the .047μF roll off a bit to the dark side. What are the values of the others?
Also, have you used the vintage braided wire before? No big deal if you are familiar with it.
If not, I can put up some pics and a video on use and soldering technique.
Keep us posted on your progress. Love the pics!

RS Superpot...Basically a 25% - 30% Taper Audio Volume Pot:
_______________________________________________________________________________________________________________
Linear Volume Pot (50% Taper):
And yes, I use Linear Volumes the majority of the time.
Willy

Does it matter the taper percentages of audio pots, when using them as tone pots?
In answer to this, yes. But, not enough to make a significant difference. As long as you are using a 10% or 20% taper, the difference as a tone pot is small. Not enough to worry about. I still favor the less expensive 10% CTS Audio pots for tone. Unlike using them for volume, most would be hard pressed to tell the difference. The ones I have bought from Hoagland Bros. have always been 10% anyway. I'm not sure if they even know.
Onward and upward!
If you go with 50's Dependent using Linear volumes, I'm guessing you are going to be very happy.
The only disadvantage to going 50's Dep. IMHO is inconsequential. As you roll off the tone, there is a very slight
drop in volume. (minimally noticeable) Nothing you can't correct with a slight volume tweak.
Avantage: Most people that go 50s rarely go back to modern. Many say it is like taking a towel off their setup. The sound does not darken as you turn down the volume.
As a matter of fact, I just redid my 1976 Gibson L.P. a week ago using the very pots you are talking about.
(Albeit, they were long shaft):
http://forum.gibson.com/index.php?/topic/82973-lp-redo/page__view__findpost__p__1145594
I also just refinished my Epiphone L.P. this morning:
I bought it when I first joined the forum. The wiring is not as pretty as my more recent jobs. It was my very first mod.
I didn't even know how to use the vintage push-back wire which I used on the switch. Instead of pushing it back, I unraveled it with a tooth pick and twisted the strands with my fingers. LOL
Still, it was good enough that all I changed this morning was the capacitors and their position to 50's. And, of course, the wire grounding the tone pot lug.
Anyway, on to the volume samples. Keep in mind that there is no right or wrong!!! It is about how you like to use your controls on your guitar......So, kick your volume up to 7 and decide which you want.
All samples are 50's Dependent......this will take two posts (you can only put two media per post)

TBM,
First,
Did you get a chance to read this?:
Next,
Are you going 50's Dependent or 50's Independent?
If you let me know, I can give you a few facts and put up some sound clips of different tapers in use.
(As I did for Plus Top Dan in post 15 and 16... although I put up Modern dependent clips for him)
Addition food for thought as you get started.
The short CTS in your link and your pic look like 10% taper audio pots. (naturally I can't be positive) If they are and you use
them for volume pots in 50's dependent (my personal favorite) you will likely be disappointed.
90% of the volume taper would happen between 10 and 8.....the rest of the taper would be useless.

also... I'm looking for the hard case though, the real one
you know where to buy?
They don't make one. I adapt them from a regular L.P. case.
Specials...(and I have a few).... are thinner guitars than the regular L.P.s
That's one in my Avatar.
A trip to a fabric store.....some sponge rubber and some cloth....a template made from construction paper ....
This is what I do:

Willy

do you know the exact price of this guitar?
No.....
I would give you between $50 and $150 for it IF I was looking for one....depending on the condition.

It's not a fake.
Welcome to the forum!
If you like it, do you really care where it is made?
or/
You just curious?

Just trying to be a helpful forum member. I plan doing this upgrade myself to my newly aquired Epi LP Custom Silverburst.
Willy

I have a new Epi SST-Studio that has an annoying hum problem when plugged into either of my two guitar amps. I KNOW it is the guitar because I've swapped out cables, amps and other guitars. The hum disappears when I touch the plate around the output jack with my finger;
Lee, Welcome to the forum!
I don't have a SST so I don't know how much help this will be.
First, an obvious ground problem. Shielding? Possible. Does the guitar have the hum when set for both amp or headphone?
Loose ground wire on jack itself? Very common problem and easy to check and fix.
How old is the guitar and where did you get it from? If it is new it should be fixed or replaced at no cost to you.
As to the shielding well, unless you got an oddball, they are all made the same. This would mean that most everyone with that model would also have the same problem. I'm not saying that that could not be the case. It just doesn't sound likely.
Other consideration is the battery run Preamp by Shadow and NanoFlex pickup by Shadow. Even if I had the guitar in front of me I'm not sure I would know how to test and diagnose them properly.
Best I can say for now is that if it were mine I would carefully unscrew the jack plate and see if the ground wire on the jack was loose. After that it would be back to the store or off to the shop.

Sorry guys,
I was wrong. One guitar is a Gibson '69 Deluxe Les Paul with P90 pickups.
One guitar is an Epiphone LP Custom with a Dream 90 Neck PU and a Mean 90 Bridge PU.
Still, just for fun, here is the link:

Also, in case anyone is interested in the Duplicator 9000:

I believe a live comparison is in order.
I have replaced the the Epi P90s in my Special (see avatar) with Gibson Vintage p90s. There is a difference.
Even taking into consideration what ever amp you are playing through it is there. It is not an earth shaking, revelation, Oh my, the sun just came up in the west difference. They do sound clearer and more transparent to me.
I do not consider it a necessary upgrade. For me it was right time right place.
I was able to buy them before the prices jumped $30 each.
As to a live comparison, I put up a somewhat blind, youtube comparison in the lounge a couple of months back.
Someone on one of the other forums had made it. It compared Gibson P90 soapbars to GFS soapbars.
It was done both dirty and clean without telling you which pickup was which 'till the end.
It was surprising how many people preferred the GFS.
If I can find it I will post the link.

Based on 2 pics???
From what I see?
Sorry...
Willy

Hope this helps...
One clip, 3 Gearhead files.
1. Clean (no mods) 2. Clean .047 cap used as filter 3. Clean .01 cap used as filter
http://dl.dropbox.com/u/21424628/Clean%20mix.mp3
The only alterations I made were to zero out the DC offset and normalize the volumes to equal settings.
Sorry Gearhead, I didn't have time to do the "dirty" clips.
I wonder if this discovery could be used to stop the sound getting slightly muted when the volume control is down low?
Bigneil,
I don't think so. (not positive) For that you need to add a resistor into the normal cap path (kills your cut in a live band situation) IMO
or...
Convert to 50s wiring scheme.
Willy

Gearhead,
Tried listening to your clips.
It took me to a web page that told me the file was not available or that I was either not logged in or did not have the owners permission to view it.
Is it just me or something else?
Is anyone else able to access these files?
P.S. Hope you got my reply to your PM. In any case I hope my post in the Lounge answers your question.
Willy
-
in theory you could just turn down the bass on the amp to get the same effect as filtering out some of the bass at the source without having to make permanent
Correct me if my understanding here is wrong.
Good point!
You might be correct!
I'm hoping that Gearhead does his test and reports back. I also hopes he does both clean and dirty tests.
Willy

For Amx,
He is not using the cap as a tone cap per say. He is using it as a filter. Instead of "rolling off" the tone he is using the higher values to filter out the lower frequencies.
Gearhead,
Good find and an interesting concept.
This is his Tone Zone clip. The first part is the pickup without mod. The second part he uses a .047 cap. The third part is with a .01 cap.
TZ Cap Shootout:
http://dl.dropbox.com/u/21424628/TZ_cap_shootout.mp3
(I hope this works out. It is the first time I have tried this type of embedding.)
With all the distortion he is using it is hard to tell if it is getting rid of the muddyness or just the low end.
It is definitely brightening up the pickup.

Seastone,
Don't know about others but I'm always interested in what someone has done as mods.
Info and Pics....
That's what it's about. (although we do get a few good laughs from time to time)
Keep us updated,
