Re: Squealing TB-6 Distortion
They come wax potted. Is the pickup new, or have you had it a while, and it just started squealing?

Re: Squealing TB-6 Distortion
Hi, I've had for 3-4 years and it squeals mostly in front of a hi-gain tube amp. If I split the coil with middle pup he squealing decreases significantly.
Thanks for the help.

Re: Squealing TB-6 Distortion
hi tanhks to everyone in this forum, this is the kinda place I like to be... Well here's the thing, I'm considering rewiring an old '91 RG770DX, love the guitar in almost every aspect excedept for this squealing issue I seem to be getting. I'm considering isolating the control cavities with adhesive foil and foam mounting the pups. I've been through all my tubes and at the moment I have the least microphonic one's in the amp. I've never wax potted a pup and I'd hate to wreck the ones I have. I have a layout of the wiring I want to do that I'm gonna post and there's also a doubt in my mind. When I look at the bottom of my guitar the switch (5 way 4 pole) it need to be mounted upside down in consideration to my interpratation of the diagram. Should I just connect to the according pins with the switch in the upside down direction? With regards to the foil shielding should tthe pots have continuity to those?
Thanks I really appreciate any help I can get before I get my claws into this.

Re: Squealing TB-6 Distortion
I agree its either the ground or potting issue. I had that prob with a X2N once. It was a bad pot.

Re: Squealing TB-6 Distortion
Hi guys, things are calm around the household today and I'm getting ready to rewire today. Ther's a question that I have regarding using shielded wire from the out and ground of the switch to the volume pot and from the output jack to the volume pot. Basically, and based on the diagram I posted, is it better to use a shielded cable for these 2 hookups or am I better off just running normal wire?
I'd really appreciate anyone's input on this, I'm anxious to get started.

Re: Squealing TB-6 Distortion
I'm not sure what you mean by shielded cable or normal wire? I got a roll of wire from guitar fetish, and wired my whole guitar with it.

Re: Squealing TB-6 Distortion
The type of shielded wire I'm talkin' about is this one:

I'm probably gonna go old school and, just run separate leads,
Thanks,

Re: Squealing TB-6 Distortion
Usually, if your guitar's cavity is properly shielded, you can use regular unshielded wires. Better if you can use solid core wires of a thin gauge, enough to have flexibility while routing wires inside.
Stranded core cables are more prone to microphonics, because the strands vibrate and "colide" once against the other. This is more noticiable the higher the gain you are using.
If you have springs on your pickup's adjusting screws, remove those springs and use a rubber tube, instead, to avoid potential microphonics issues due to vibration of such a spring, that can "colide" against other metallic parts (screws, pickup plate, etc).
If your pickup has a metallic base plate, be sure that is firmly glued against pickup's back.
If your pickup has a metallic cover, be sure that is still correctly soldered and has no free movement.
Review also the jack on your guitar. Tighten it!.
Do you have some strand vibrating free, that escaped from some soldering spot?. Any dull soldering spot?. Ground Loop?.
What about your guitar's cables?.
Are you using a good solid core cable? or a stranded cable?.
What about your patch cables?.
Check also jacks on your pedals, tighten them!.
Check input jack on your amp, tighten it!:
Check your tubes, specially V1, PI and Power tubes, for microphonics issues.
.......
At this point, I am running out of memory but, those are spots you should always check if you are runnning into microphonics issues

Re: Squealing TB-6 Distortion
I'm having the same issue with my brand new SH-6 Distortion, but it's really just my A-string. 440hz just vibrating all the time if I'm not muting the string. I've had microphonic pickups before, but I'm not sure if this would qualify, since it's really just my A string vibrating so much. Wonder if maybe it's a magnetic pull thing happening and I should probably try lowering the pickup away from the strings a bit.

Re: Squealing TB-6 Distortion
I thought one would want a Distortion to squeal
lol Hope you can get it fixed–have you tried adjusting the pickup height/pole pieces? Don't know if that would help or not...
