OK, you win, I guess I should get all the amps I've built and repaired over the years and ground the cab shields via the power supply caps since they bleed off stray ac noise.
Dude - you don't know what you're talking about. And awful ignorant and stubborn about it. Foil on the coupling caps goes to the previous plate. The plates of preamp tubes are at ground, AC. That's different than ground, DC. You don't understand that, do you?
For a guitar, the outside foil goes to the lowest potential, the tone pot.
You learned something today.

The joints are solid but they were just not very carefully cut at the factory. They used plenty of glue!

Where the finger joints are delaminating in the cabinet - I've used super glue to fix those kinds fo joints for awhile now. Use the low viscosity stuff and just let it run into the joints. It sets up fast and a few applications will fill the joint and make it nice and strong.

Pretty much all Gibsons are going to have some sort of finish imperfection, however minute. It doesn't mean it's not well made. It doesn't mean anything, really. It certainly doesn't have anything to do with whether the guitar is a keeper or not. It's the nature of the nitro finish.

My 335 is a little brighter than LP's at moderate volume. More articulate, I'd say.

It's hard to find good one, that's for sure.

Now I'm just messing with it -
Me : Does that same principle explain the relationship between the formulae for surface area and volume of a sphere?
Chattronic:
No, the principle of the derivative does not directly explain the relationship between the formulas for the surface area and volume of a sphere.
The formula for the surface area of a sphere is A = 4πr^2, where r is the radius of the sphere. The formula for the volume of a sphere is V = (4/3)πr^3.
While there is a relationship between the surface area and volume of a sphere, it is not a derivative relationship like the one between the area and circumference of a circle. However, the surface area and volume of a sphere are related in that they both depend on the radius of the sphere.
For example, if you increase the radius of a sphere, both the surface area and volume will increase, but they will increase at different rates. The surface area will increase at a rate proportional to r^2, while the volume will increase at a rate proportional to r^3.
This relationship between the surface area and volume of a sphere is important in many fields, such as physics and chemistry, where spheres are often used to model particles or objects.

Holy moly - I've wondered this ever since high school and I never knew. This thing's pretty smart!
Me: Why is the formula for the circumference of a circle equal to the derivative of the formula for the area of a circle?
Chatmaster:
The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. The formula for the area of a circle is A = πr^2.
To see why the circumference formula is equal to the derivative of the area formula, we can differentiate the area formula with respect to r:
dA/dr = d/dx (πr^2) = 2πr
This means that the derivative of the area formula is equal to 2πr, which is the same as the formula for the circumference of a circle.
In other words, the derivative of the area formula gives us the rate at which the area of a circle changes with respect to changes in its radius. This rate of change happens to be equal to the circumference of the circle.
This relationship between the circumference and area of a circle is not a coincidence, but rather a fundamental property of circles. It is a consequence of the fact that the circumference of a circle is the derivative of the area of a circle with respect to its radius.

It's not buying this -
Me: Did the Fender Telecaster guitar define the soundtrack of American Baby Boomers' youth?
Chatmaster:
The Fender Telecaster guitar certainly played a significant role in shaping the sound of American music in the 1950s and 1960s, which was the era of the Baby Boomers. As one of the first solid-body electric guitars, the Telecaster was instrumental in the development of rock and roll, country, and other popular music genres.
Artists such as Buddy Holly, James Burton, and Roy Buchanan helped popularize the Telecaster's distinctive twangy sound, and it became a go-to instrument for many musicians of the era. The Telecaster's versatility and durability also made it a favorite of working musicians, who could rely on it for everything from rockabilly to blues to surf music.
So while it's difficult to say whether any one guitar "defined" the soundtrack of an entire generation, the Telecaster certainly played a major role in shaping the music that Baby Boomers grew up with and continue to enjoy today.

I always figured people did relicing so they'd look like they've paid some dues that they really haven't. Like ripping holes in your jeans 'cause your knees never touch the ground.

Nice one!!

I know... it's just crazy, isn't it?

I think I've seen the Gibson workers user a little tool like that. Nice.

Here's the frequency response graphs for three different amps with tone controls at 12:00. The yellow line is a '57 Fender Pro. Pretty flat. The green line is a '66 Fender Deluxe Reverb. Big midrange scoop, lower gain. Different kind of tonestack. The blue line is the '82? Dumble Overderive #102 amp, Robben Ford's amp, with a blackface style tonestack but a mids pot that's got enough resistance to dial out lots of mids. So, the Dumble is way more like the Pro, despite having a tone circuit more like a Deluxe Reverb. Now I'm supposed to mow the lawn. 🙁Check it out -

That’s too bad 😬
😁. I've already drilled out the body some to accomodate a different bridge, so it's already been kind of messed up.

I just finished renovating my wife's bathroom, top to bottom. The light fixture's a little crooked, so I have to fix that. So she's good to go, so to speak, and I'm free to mow the lawn, prune all the fig trees and everything else that's on the list.

So sorry, Ron. Lots of love from us. It'll take time, but it'll be o.k. 😢

Funny though, ya never see videos of tent cities in Florida...
That's because there's no bars in tent cities.

Florida is good because it's like a sponge. Sops up the people who are floating around.

I'm pretty much the go-to amp guy on this forum. I've fixed a few hundred amps for the public and built about 25. My biz is Tennessee Amplifier. I only work for private clients and I'm a licensed Professional Engineer.
I stay current with all this stuff. I don't just read something 40 years ago from one wrong reference in one book and then go on to do the wrong thing for a whole career. I'm an engineer, so I don't make up stuff, I do what the industry standard is. You've cited one of Weber's books and it's the only thing I ever read by him that's different from the rest of the industry does. You should check with some other references if you care about it.
If you need any more help, I'll have to start charging. Hundred bucks an hour.
