I didn't want to hijack the tele threads but it was something that Dr Bob said in a post and something i've noticed myself about pot values...i have a vintage stack in the tele neck postion(stacked humbucker for noise cancelling) but i have it split with a mini toggle and up to recently i had a hot rails in the bridge... i put 500k pots into the tele because i reckoned thats what you would normally put into guitars with humbuckers...now that i have put the original tele pickup back into the bridge i should put 250k pots back in but i really like the 'bite' i'm getting from the 500k ones....i also lowered the duncan neck pickup down as low as it would go to compensate for the lower output fender bridge one...i'm getting a nice 'twang' from the guitar and it's become a 'go to' guitar again for the first time in years....i remember Dr Bob saying that his tele has 1 meg pots.... very high for a single coil guitar according to all the research i've done on this subject..but i have to say even though it's not correct,the 500k pots are working for me and have given a part time guitar a new lease of life....

I think that Tele bridge pickups needs to be tamed by 250K pots, but on the other hand you can compensate with the tone control.
Another trick is to go to your local pot shop and measure all their 250K pots and buy the one that has the highest resistance, those things can vary a great deal.

Hi FRANZONI & Guys

If you want some of the Nitty-Gritty - my Tele is a
1992 MIJ 52RI Honey Blonde. with vintage pickups & cloth covered wire.
Ash Body.

I have internal pictures of the control cavity, if you want me to PM some to you, but they are really large hi-res files.

The pots as it came were both 1M, I haven't & will not modify this guitar, it stays stock & sounds great, the Vol pot seems to have a bypass (very small) cap on it, but I wasn't able to read it's value.

Let me know it you want to know anything more about it.

The 1M pots put very little loading on the pickups, but It's not overly bright even on the bridge pickup, & as Goran wrote, you just back off, which I always do anyway.

Regards Dr. Bob

Hi Doc and Goran

reading your post on you tele is what gave me the idea to leave the 500k pots in mine for the single coil..personally i don't find it too trebly and when the neck pickup is in humbucking mode it still retains the a bit of twang and doesn't get too muddy.....because this is a jap squier and the body is basswood might be something to do with it i'm not sure..... also the fact i'm going into some pretty old valve amps as well which i find are usually a little darker sounding than some of the newer ones.....seems to work very well with the little selmer 15 watt.........

iirc vintage Teles had .1uf caps with the 1M pots to tame the extreme highs, but keep the twang

Talking of pots how many people do all that faffing about adjusting pots during songs? i always hear of 'backing off volume to clean up', finding sweet spots etc. Me i just leave 'em on 10 (or 11 if i can ).

i have got a BariToneStyler to be fitted in my Baritone Jag which i hope will encourage me to mess with the tone pot more at least.

I agree i find that i only do it if i have the compressor or the overdrive on which give me a volume jump i might back them off with the guitar slightly to get a certain sound without turning off the effect but mostly if i'm playing clean the guitar is up on 10.....

With Fuzz Face type of fuzzes using the volume pot makes a hell of differences.
Put the volume on 10, really fuzzy, put it on 9 and overdrive comes, put it on 7-8 and you have instant clean. It has something to do with the loading of the pickups.

I have done some research on pickups, as I am modifying an old matsumoku semi-hollow. I found this about Tele pickups;
The standard pickup arrangement for a Tele is a large bridge pickup and a small neck one. The coil resistance of the bridge pickup is about twice that of the neck and this is reflected in the tone and output, in fact many players find the neck pickup to be somewhat ineffective. However, the distinctive "Snappy" Tele sound is achieved with just the bridge pickup and the bleed capacitor which is normally fitted internally.
A very small capacitor is fitted as standard to a Tele between the slider of the volume control and the output. In simple terms this means that as the vol. is turned down the treble still bleeds through whilst the lower tones are faded. An effective setting for the volume is about ¾ full as this gives a treble boost, which brings out the highs, this combined with the fat tone of the bridge pickup is the Tele "Sound."

hello pedals.......

yep.....i reinstated my original bridge pickup a while back because the duncan hot rail was a bit too muddy for that trad tele sound,the reason i changed them originally was because the neck pickup was crap and the guy in the shop did a deal for the bridge as well..i remember at the time i was pretty happy with the bridge,don't know how i got talked into that one.....i have the duncan vintage stack still in the neck position with a coil tap.....this is a stacked humbucker when tapped it ovbiously loses it's hum cancelling but there is a more trad single coil twang off it..the cool thing is in full humbucking mode it has a nice fat sound,i like to think i can get that keef richards/any summers thing going on with it without having to route for a proper humbucker......the compromise is the value of the volume pot to use...i had 500k ones in with the hot rails so i left them in as they work well with the neck,probably a little too bright with the bridge pickup and some amps(sound ok with my valve ones but very bright with a marshall tranny combo i use in our rehearsal room) i suppose a solution(as suggested in the link) could be to install two volume pots and do away with the tone(as i seldom if ever use it) with different values for the two pickups,i think the one of the john 5 or the ritchie kozen sig teles are wired this way.....
