Thanks a lot. I just held the paper by hand. I’ve done woodworking forever, so it’s pretty natural for me. One thing you can do is to guide your outermost finger along the edge of the box to keep a straight line. If that makes sense.

you have described my approach to building. Works fine. If you’re not using a battery or other switching involving the ring of the jack, then mono jacks work just fine.

Here's a raw enclosure challenge:
- a nice even cross-hatch:
The old Bugatti's are really stunning. This one's a 1926 Type 37A and the engine is hand-scraped while the firewall is engine-turned (as are often the instrument panels in the cockpit).
I used to have an even nicer example of hand-scraped cross-hatching on an engine, but pic must be on my old computer thus the linked pic above. If I could get cross-hatch by hand an enclosure to the Molsheim Bugatti standard, I'd be an extremely happy man.
The Pur Sang crew in Argentina do a pretty good job of replicating the hand-scraping of yore...
I've tried sanding cross-hatch by hand, but a bench-grinder worked better...

Deadlifts will give you a big butt. It's why all the girls at the gym do them. Also hip thrusts but those look too sex-like for my tastes.Thanks doll.
My wife says I have no butt. I can't see back there, and TBH I'm okay with that.
Speaking of leg training, here's inspiration from the Quadfather himself. Skip to the end for the most stimulating part

When I was managing a MTB team as well as racing, myself, we're all gearing up by the race van and somebody commented to me I had a small butt for such a sport; The young studly star-racer on my team said "He doesn't have a butt, his legs just go straight up into his back!"
I said "What the hell are you doing looking at my butt?"
He said "I'm forced to see it every time I lap you."
OUCH!

How does the forward voltage of a diode related to the decibel level of the signal leaving? Say I have a hard clipping distortion circuit and I replace 1n4148 diodes that have a 0.7mv forward voltage with red LEDs that have a 1.8mv forward voltage. How many more decibels would be allowed through the diodes?

Not mV, Volts. Vf for 1N4148 is around 0.7V = 700mV. Also, the Vf you read in a datasheet or measure with a meter will not be the same as the clipping voltage, but it will be in the ballpark. The dB difference is 20*LOG(Vf1/Vf2) where LOG is base 10. In this example, Vf1 = 1.8V and Vf2 = 0.7V. Therefore, the dB increase going from 1N4148s to red LEDs is approx 8dB, which will be noticeably louder. The tone will be different too because the knee of the I/V curves is different.

Ok. I have another question then. Bare in mind I haven't had a math class in a long long time. What do you mean by base 10 in that equation? If I see base 10 I assume it means a number system based on tens, vs something like binary based on two values or an octal system based on eight.

Do you know what LOG means? If not, look it up. There are three common LOG bases. "Natural logarithms" are base e. If you see LN(x) in an equation, it's a natural logarithm. dB uses base 10 logarithms,represented as LOG(x). Octaves use base 2 logarithms, represented as LOG2(x). They are all the same function, just different scale factors.
Log is the inverse of exponential, if that helps. 10 squared is 100. LOG(100) = 2.

Ok, like a logarithmic pot versus a linear. I knew there were a couple different logarithmic tapers used in pots from watching Psionic Audio amplifier videos. At first I thought maybe you meant 20^10 (twenty to the tenth power). That's really helpful. I was trying to figure out if the LEDs would let enough signal through to use a full TMB EQ without killing the signal. Gotta take into consideration the minimum gain in the noninverting op amp gain stage beforehand.

You will probably want some make-up gain after the EQ. Typical loss in a Fender/Marshall TMB is 10 to 20 dB, depending on settings. Or you could stack LEDs or diodes to get a higher clipping voltage.

What's a harmonic percolator supposed to sound like?
My only experience with playing one was a pedal my friend had from a small builder. I thought it sounded awful and made everything sound only worse.

What is the effect used on bass at the beggining of this song (1996) ? enveloppe filters ? Which one ?
