CBS Era TELE WIRING - "1-Meg" Volume "250k" Tone

Maybe some of us have been missing the boat?

part of that overlooked later 60's brighter / twangier tone would have been this one meg pot and the treble bypass cap on the volume..

AWESOME! I'm going to recommend this wiring to customers seeking that era of Tele tone!

[tele salivas]

Holy Frijolis Mr, Mare, you may have stumbled upon my holy grail,,this is just incredible, I think I know what I'll be doing today! Thanks mang...

To each his own, but this one is not for me. I LOVE what this does to the neck pickup when wide open, but the bridge pup can be a bit harsh. My biggest problem with this set up is it is hard to use at a gig because the taper of the 1 meg volume pot is so abrupt. If you take out the .001 cap, it is almost like an on/off switch, if you leave it in, when you roll back the volume the treble stays in the tone but the bottom and middle diminishes with with the volume roll off. This gives the perception (to my ears anyway) of sucking the balls out of the tone without dropping volume that much.

My sollution is to put a .220 resistor in parallel with the .001 tone cap, from the middle to outside lug of the volume pot. With this set up you get all the spank and openness of the 1 meg pot, but the volume knob behaves in a more usable way, especially for quick changes on the fly, with a less abrupt taper and less percieved tone sucking.

[Don Mare]

OK, I finally tried this out and thanks for the GREAT TIP on the resistor too.

the volume swells are perfect now!

I've never played a Tele that could twang like this - dreamed of owning one - but now the dream is a reality - I used my new Road Worn Tele for the test pilot -
it was already Twangy - thanks to the OEM Factory installed steel barrel saddles! and they were raised way up high - so the twang was already great -
but this wiring put it in Bakersfield Country Hog Heaven!
I also used Pure Nickel Ernie Ball .11's -
next I wound up a Staggered AlNiCo 5 / 6.7k Relic Bridge pickup / and a AlNiCo-5 / 6.15k Neck in a Nickel Silver Cover

it was too late to crank it but MAN_O_MAN did this TWANG and REEK Of Country TELE For DAys! -- can't wait to crank it thru the Twin nice and clean and LoUd! Yippie_

BTW.. not harsh at all here - I understand Machine wind pickups do the harsh thing pretty easily - but a Hand Wind with a nice wind pattern eliminates any harshness to start out - and I took it up to 6.7k to be safe - just in case the One Meg was the culprit - but its perfect here - I'm truly amazed- can't wait to offer this on my web site as another style of a Bakersfield set up & wiring mod.. for guys to try out..

[Amby]

Nice looking guitar Don - enjoy it.

[tele salivas]

Great Don! That's what I am hoping to hear out of my tele.I'm still waiting on a 1meg pot , but that road worn looks beautiful, I think out of all the 'relic' guitars, they have done something special with this line...I just may have to ring you up...

My 1966 Fender Esquire has 250k pots for volume and tone. I always thought this was normal and unchanged from 1950 to present day. Am I wrong?

[spankdplank]

Starting in '68 or so Fender started puting 1 megs on the volume, with a .001 treble bleed cap. Then by late 68 or 69 they went to 1 megs on both volume and tone. This lasted until the early 80's.

I know its on 1968's for sure -- we need to check with 67 owners and we can find the start date of 1meg use.
the end date would be of interest too..

I do remember that every now and then a 68 would knock my socks of with Tele Twang that would warm a country pickers heart!

[spankdplank]

For what its worth, I have an all stock maple cap neck 68 with an October neck stamp, no diagonal wiring chanel, a pearl backed pickguard and all cloth wiring. From these indicators, I believe it is a very late 68. It has two 1 meg pots ( w/ '66 date codes) and a .001 teble bleed cap. The bridge is 6.3 DC and the neck is 6.8. No wax potting. A twanging monster of Bakersfield tone, with one of the spankiest neck tones I have ever heard. I kept the .001 cap but added a .220 resistor in parallel with the .001 cap. It made it so much more usable live.

[KingOfTheRoad]

Hey All,

Do you guys mean 220k for the resistor?

Cheers

[Don Mare]

I've seen values from 120k to 300k on the resistor used "Kinmans Pickups" under "perfect Guitar" used to describe what values do what..

this is Stew Macs kit pictured

[spankdplank]

Sorry--I'm a pretty dull tool on the electrical tech stuff. I thought it was a .220 resistor I used, but you are right, it was 220K. I wired mine in parallel with the .001 cap, as in Don's dagram.

me too- I was measuring resistors at midnight and flipping the meter settings trying to locate a .220 - hehe!

also the cap can go from 0.001 to 0.003 range

Humbuckers and 250k to 1 meg pots may require some experimenting

I'm sure mine is a 150k with a 0.001 cap it really sweeps well - I can do nice pinky volume swells without any jumps

[1962guitargeek]

I have a silly question Don - is the 1 meg audio or linear taper?
Thanks

If you tried to use a linear taper pot as a volume control you would be most unhappy with its performance. The sound level would go from nothing to almost full volume in about the first ten degrees of rotation and the rest would have almost no audible effect. This is because the ear responds to sound logarithmically rather than linearly. That's why sound engineers use the decibel which is a logarithmic function of power.

I do take all my pots apar - by bending 4 tabs - and I clean out the orange looking grease - because its so waxie that it stalls rotation and prevents the pot from being used for Pinkie Swells - once I remove that grease the pot swings like Roy Buchanans on a good day! hehe

Which 1 meg taper pot did you wind up with, or did you say and I missed it? ;)

[bosstone]

Does doing all this take away from the guitar having good blues and rock sounds?

For all practical purposes, Country is guitar with a high power amp for clean headroom.

Blues is a guitar with a lower power amp so you can overdrive the power tubes for some grit.

There are exceptions, of course.

[1962guitargeek]

Thanks Don I just happen to have a couple of 1 megs lying about. (audio taper)

I hope its a Audio ? - acts like one - but I honestly dunno - its just one I had saved here for a few years

- but today I got some shipped here from ACME ( all audios)


Fired up the Twin today - it cracked a while - cause it had not been on in months then it worked fine.. tried the Clean Head Room test -& I Loved it!

Yah, I have known that for a few decades. My question is how this mod works in the different applications...with different amps. Can the pots still be adjusted to sound good for different applications of does it cut off the frequencies that would be needed or make it much less desirable. Early Broadcasters and Teles have been used for over 50 years for all kinds of applications.

[tdowns]

I generally wind up with a 330K resistor across the treble bypass cap when using a 1meg volume pot. I use clip leads to connect another test 500K pot across the treble bypass cap. I tweak that pot until I get the best taper for me. I read the value of the test pot and install a fixed resistor that is closest to the resistance I read.

The 1 meg volume pot all about unloading the pickup and allowing its inductance to be more resonant with the cable/amp capacitance. Bear in mind to that a max CW tone pot is nothing but a capacitively coupled load resistor. Increase that tone pot resistance and get even more resonant highs. Some folks can't handle it, but me coming from the Don Rich era, there is no such thing as too much treble.

This is an interesting thread, keep the info coming!!

Does putting a resistor on the 1 meg pot change the value of the pot? I am not familiar with it but I read somewhere that you can change, say a 500K pot, into a 250K, or a 1 meg pot by adding a resistor? Would that be using different lugs or how does that work exactly?

TO Change a 500k pot magically into a 333k pot do this:
take a 500k pot and a 1meg resistor and attach one end to the incoming hot on the Volume pot
( from the jack) or center lug on the pot - then ground the other end of the resistor to the back or the pot - this will turn the 500k pot into a 333k pot

( By the way this has nothing to do with what we were talking about - as far as treble by-pass mods, ok)

So putting the resistor on the 1Meg the way you guys are talking about does not change the value then, only the taper? Im going to have to try this out

[tdowns]

I was talking about a resistor between the center wiper and the input (pickup) terminal. When the pot is max clockwise, the resistor and treble bypass cap is shorted out and not in the circuit. Therefore the load on the pickup is 1 meg plus the tone circuit. As you turn it down, the fixed resisitor helps the taper.

I 've learned so much on this thread, the language has been much clearer than in lots of other similar threads(either that, or I'm finally catching on)man I love this place

[Lerb21]

Hey guys,

I've never tried to actually custom wire a Tele (I know how to solder though), and I really wanna try this wiring. I have some idea what most of the terms and parts are, but I have no idea where to get em'.

I need:
1 1meg Volume Pot
1 250k Tone Pot
1 100pF thingie (I assume these are capacitors or something?)
1 .05uF thingie

and well thats it... If someone could provide me with some links as to where I could procure some of these, I would be utterly delighted.

Also the current three way switch in my Tele is not standard it got the eight to a side like this:



Thanks guys!

[tele salivas]

Try Stew-Mac, their catalogue is wondrous ..

[Lerb21]

Hey guys the diagram disappeared (for me anyway), does anyone still have it?

I save a lot of these schematics etc., and have a library locally on my PC of tons and tons of ideas and documented text/pics etc. A lot from the TDP.

I just got some 1 Meg posts in to try this out. Got an excuse to put together that 07 Alder HWY1 into a guitar again now. Some low output PUP from a Paisley RI and steel saddles too...

[voodoo_idol]

I'm just now finding this thread and would like to try this wiring on a tele project I have underway. It looks like maybe there was a schematic posted here that is now gone. If so, can anyone point me to it or email it? Thanks in advance. Mark

[voodoo_idol]

OK, I think I found the schematic on Don Mare's website, a file called "440_modern_tele.jpg". A google image search links it to this thread in the past. I'll give it a try.
