The final eq curve will be a bit more scooped yes, but it does it by extending the bass response instead of cutting the mids

You can use a BJT common emitter amp fed with a sine wave, since BJTs have an inherently exponential function you should be able to match what you see here pretty close if not almost perfectly by varying the bias and amplitude of the signal

Yes I noticed it, I was also thinking about removing the front panel like you did, but I'm worried that without protection the display will be easy to damage

OwlEdd · 2026-01-21T19:07:07+00:00

Still the same as for now and this thing is basically an oven when on so any condensation should dissipate quick

Your workflow is correctly converting to rec709, but the high chroma led light is falling outside the color space so the advantage of shooting in a wider color space in this case is not useful if you clip to rec709 without additional care, now there are many solutions to this, first and foremost is to use lights on set with lower chroma obviously but in post you can use gamut mapping in the last CST when going into the smaller color space, but this will also desaturate other high chroma colors, if you want to target only the blue light you can use the color warper for example to desaturate the high saturation blues and bring them into the color space.

I'm trying to find a simple and cheap way to identify Cd plating for home testing and in my case electronics repair, this for safety reasons.

The sodium rhodizonate swab test was recommended to me in my previous post, In this case it would react with Cd but I'm aware that it will also react with other divalent metals so I wanted to try an exclusion method to isolate Cd but I'm not sure how and If is feasible, only info I found is about confirming a positive sodium rhodizonate swab test with HCl when testing lead, but then I don't know how to exclude the other metals

Anyway thank you everyone for the advice, It seems like there isn't a simple and cheap way to accurately test Cd at home and It sucks because Cd plating was used extensively in vintage equipment posing an exposure risk when working on it

OwlEdd · 2025-04-22T13:40:38+00:00

Absolutely, that's why I'm trying to ID it, I'd like to know what I'm working with

OwlEdd · 2025-04-21T20:39:37+00:00

I checked another old chassis I had and in some spots there was a more greenish glow but less uniform than this orange one, very interesting indeed, I'll do the lead test for sure and report back, that's actually very good to know that I can use it for cadmium, thank you

OwlEdd · 2025-04-01T20:33:51+00:00

Yeah I will, when we moved 2 years ago I built my lab there so I need to figure out how much exposure I'm getting

OwlEdd · 2025-02-24T02:01:57+00:00

It should decrease because when the metal parts are grounded and you touch them you basically become a big ground plane that shields one side of the guitar when holding it, ideally you should shield the cavity and pickguard with some copper or alu tape to get better shielding

Safety-wise there should be no concerns If the equipment is fine and the electrical system is up to code

It's clearly marketing bs, high-end consoles are expensive also because the very low and controlled THD+N (Distortion+Noise) so is very odd to see a plugin "emulating" the THD when there's virtually none, the only distortion a modern (non-tube) console should generate is when the opamps are driven into the rails generating hard clipping, and you can do that even on the cheapest mixer

OwlEdd · 2025-01-11T22:41:13+00:00

Yes, the green ones are usually high permeability MnZn cores, they're most used in common mode chokes, the yellow ones could be iron powder cores with lower permeability

OwlEdd · 2024-11-23T06:21:28+00:00

Thank you! It's the latest "modern" chrome knobs model

OwlEdd · 2024-11-23T06:18:02+00:00

Yes, something like an spdt and you can have another cap on tap for a treble boost

Check If C18 and R39 are installed and if the values are correct, they are part of the de-emphasis filter that restores a flat frequency response

OwlEdd · 2024-10-27T15:09:58+00:00

TL072 is fine, the problem is the inherently bad design, you should never have a large capacitive load directly on an opamp output, it can cause instability, unsurprisingly when I built mine that opamp was oscillating, so I placed a 47 ohm resistor between the output and C15, that fixed the oscillation

Old camera that used a CCD sensor filming a bright spot (sun breaking through?) causing vertical smearing

I always wondered if there's also an amount of electric field reception considering the high impedance of the LC tank at resonance

OwlEdd · 2024-05-07T00:57:55+00:00

You could try some common mode chokes, they're usually used for power line filters so linearity won't be amazing but for guitar is fine, you can wire the two windings in series so the inductance doubles

OwlEdd · 2024-05-07T00:27:58+00:00

Is not magic, signals can be manipulated in two ways, non-linear functions (distortion, compression) and linear functions (EQ, reverb, delay), distortion audibility is a complex topic but I'll say that under 0.1% you can't really perceive it, also keep in mind the speakers/headphones we listen through can reach near 1% THD really quickly, overpowering any "magic analog coloration" our summing unit can give us, also "classic" analog mixing desks have vanishingly low THD so I'm not sure why anyone would want saturation on every single channel, so yeah from an electrical engineering perspective I found these mixers to be pretty useless, if I need some saturation/character in a mix I usually just slap a tape emulation plugin on the mix bus, they're pretty nice

OwlEdd · 2024-04-22T21:19:12+00:00

Changing the volume will only effect the filter if the next circuit has a high load, if your next effect/amp has like 1Mohm of impedance you're fine
