debug hum er rations

I experience some hum level increase when rolling guitar vol back from 10 at times.
I usually dial in gain / tone with vol around 6-7.

Dont recall conditions, which amps or pick ups, but it seemed counter intuitive and caused me to notice it.
This is while not playing but my hand(s) on the strings.

I made a mental note of it, then "fixed" it by "my fingers go up and down".
Wait, thats Lynott / Thin Lizzy; by resuming playing.
I dont have the concerns one would have in a studio environment, as that would also require the ability to actually play the durned things.

I got some of that better shielding paint @Robert Herndon posted a while back.
It is on the island of misfit things to do that I cant find time to do, with all the others.
 
So Im not certain what the issue was -- the Humbugger mother trucker should be here Thursday

Im not convinced its a ground issue--
Im also not convinced ALL the listed guitars would have the identical ground issue--you see the innerds of the PEavey UNity bass -(shoddy shielding at best)
the Squire Jagmaster has ZERO shielding and a HUGE swimming pool cavity behind an even BIGGER pick guard---has some el cheapo china Gretsch clones in it --
(could be ANY # of issues -- or several-- causing that hum)

ALSO -- not ALL of them react the same -- FOR THE RECORD -- some (LIke the Les Paul Jr.) are basic P90 hum---

While I appreciate your diagnosis Dr. Bastard -- I cant say for sure or against that it is a grounding issue

The Squire (brand new 2018) with factory shielding paint -- very thick very well done throughout all cavities -- reacts the exact same way -- roll back the volume hiss increases--turn tone to zero-- goes away---all connections are good-- brand spanking new guitar-- not a scratch dent or an open box even --

I am going to say sitting in a small corner of a small room with 20+ year old wiring-- MULTRIPLE computer screen -- wifi signals--1 regular light 1 florescent desk lamp--- all those things are probably way more CONTRIBUTORY to the noise-- in certain guitars----

regardless -- shielding "fixed" it--

so -- life goes on -- and I am probably going to trading that thing off soon anyway =---

I couldn’t say either way from here.
I’m not gonna either.
In that humbucker guitar...I am suspicious of one over the other, but who cares...it’s better now...and that’s all that really matters.
Either you provided a more solid path to ground, or you have shielded some
non-humbucking humbuckers. Yay!!!!
 
different from 1 guitar to the other -
it goes away when you turn EITHER the volume OR the tone to 0
but when the volume is on zero you cant HEAR the guitar...... you Rap scallion you ;)

Mini Humbuckers Versus Full Humbuckers

Q: What do the Gibson Les Paul Studio ’70s Tribute mini humbuckers sound like compared to the 490R/498T pickups found on the Les Paul Studio ’50s Tribute? I’ve never played mini humbuckers before.
A: Mini humbuckers are tonally sort of a cross between a humbucker and a single-coil, in the same ballpark sonically as a P-90, but humbucking (meaning no noise) and with a bit more mid drive. The pickups in the Les Paul ’70s Tribute are fairly high output, so they are a bit thicker and hotter than some other mini humbuckers, but still with that single-coil-style top end bite and chime.
The Gibson 490 pickups are thicker and darker sounding, with much hotter output than the mini humbuckers.


AND the 3 guitars Ive ever had the pleasure of playing with them all were more P90---Single coil ISH in function and tone and with a bit more "sizzle" to the pups---in all forms and function

Ok....

Mini-humbuckers ARE true humbuckers because they satisfy the single and only duty of a humbucking pickup...They buck the hum!

This poorly-worded article by Sweetwater (which disappoints me because I like Sweetwater) is misleading because they use the term “Full Humbucker” when they really should use the term, “Full SIZE Humbucker” (meaning a traditional, PAF-size form factor).

The tonal comparison they make with single-coils and a [Full Size] Humbucker is meant for tonal description, not function.

My mini-Humbuckers “buck the hum” just as much as my full-size humbuckers.
 
I can tell you in 2 SG's -- back to back (both shielded ) both mahogony bodied rosewood fret board GIBBOS -- they sound VERY different from each other
(mini hum vs hum) bucking

THESE
are by definition humbuckers
jagmaster.jpg
and they HUM sizzle crack n pop

THESE are humbuckers---
explorer2.jpg
BOTH are 100% UNSHIELDED bodies-- the Explorer is DEAD quiet

in the exact same spot in the cosmos 1 is lovely one is damn near unplayable ---



its ALMOST like you all DOUBT what I am saying (at least that is the "vibe" Im getting) --- weather YOUR guitar hums or not is truly NOT the case in question here--- or the TOPIC of the thread--weather YOUR Peavey or Gibbo or Eastwood-- or Homegrown weed wacker---what have you, et all hums -- in your usage is, not what the post was about -----

FRANKLY ITS ABOUT ME---- ALL ABOUT ME---- MUWAHAHAHAHAHAHAHAHA ha
and my issues--- (oh there are SOO MANY)

and in 1 case (the FIRST of the test situation--- ) the SHielding fixed the problem

step 2 -- is the HUMBUGGER-- and how IT compares to the shielding to FIX said problem -- for myself or OTHERS out there having a similar problem---

tis a publix service announcement so to speech (Southerners will get that) ;)

---now -- can I get 2 homegrown weed wackers to go please???????
 
AWH--- but I dont know the answers -- :)

I think we should have a SWAMPTASTICAL LUAU over at Tridents Cement pond -- Ill bring all the offenders and we can HASH this thing out proper like -- and party -- and grill foods and listen to muzacs

Then Hackmaster can do a cannon ball and splash all the ladies while we laugh and stare at the wet t-shirts ..........

o.k. ?????

All together??? lets GO!
 
@eSGEe - Stopped by Guitar Sinner tonight for a speaker cable. Tech asks me to look at a new 2017 Gibson Les Paul. It buzzes like a single coil so the customer took it to the Gibson warranty station. They replaced the PCB and switch under warranty.

Guitar still buzzes, so they brought it to the tech at Guitar Sinner.

I asked the tech to plug it in and turn it on...the touch the bridge pickup. When he touched the pickup, the buzz became louder.

He looked at me puzzled and said all the grounds are verified.

I told him, "Change the bridge pickup." (I've been down this road a dozen times)

He looked at me like I was a lunatic and said, "but all the grounds have been tested with a multimeter!"

In my work bag I just happened to have a pair of Gibson 490's with quick connects that I took in trade for a pair of Gibson/Wildwood pickups. I grabbed it from my car and told him to put it in.

Guess what??? The loud buzz when you touched the bobbin stopped completely, although the guitar was still noisy, as the unshielded Gibson's, it was a huge improvement.

I made a You Tube video of the exact same problem on my 2016 Gibson Les Paul 50's Tribute, so I knew exactly how to fix it....

AMENDMENT :
testing further this thing
29581

hums (at all vol and tone leves OTHER than 0) if hands are not touching strings----

in 1 or 2 pup position -- the VOLUME level doesnt effect it (till0)

SO
I BELIEVE this COULD be a BAD GROUND----or pot--- or shielding--- its NOT the cord or the amp--
might be the chicken tetrazzini --......

Ok...on all three of my brand new 2016 Gibson Les Paul's (two 50's Tributes and one Studio) they would hum if you were not touching the strings (not to mention pick up two-way radio transmission interference from the public works and police at the nearby University) but this hum is stopped altogether by shielding.

I've gone as far to not only test grounds for continuity but also for resistance levels....

Make sure it is an alternating current (AC) adapter and not a direct current (DC) adapter. The Hum Debugger won’t work with a DC adapter, and it may damage the pedal.

The vast majority of guitar pedals use a DC power supply, so this is a difference you need to watch out for.
