If you were to start with modeling/DSP/IR-in-a-box programming in 2024, where would you start? I've got a couple IDIOT ideas I want to try out and I'm fine programming in C++/C/Python/Assembly etc. have worked with microcontrollers and ARM. I was going to get one of these https://www.analog.com/en/design-center ... odule.html ?? I don't know much, just wanted to get started to tinker, but didn't want to get too far buying stuff and working if there was a 'newest awesome standard' to work with and I didn't know it? this might be some FM benadrian lure, maybe someone else has some insight

...Maybe this is a big question that fits somewhere.

I don't know if that Sharc module would work, but Helix is Sharc-based, so I don't see why not.
There's a lot going on, and luckily I don't do any coding. I understand the analog theory of operation. Some smart DSP humans can make DSP tool to modify audio, but they do not know the intricacies of analog guitar circuits. I'm lucky to just get to use software built by someone else to reproduce analog circuits in a proprietary digital form.

This non-functional factory blem/seconded Jazzmaster neck (https://www.ebay.com/itm/134900826316) says:

"Functionally, the truss rod turns fine. The neck is straight when it is loose and when tightened revealed a wavy relief. It will be functional but may have fine tuning issues. I have not strung it up."

This sounds like it's semi-functional. In a case like this, is the wavy relief be more likely caused by a defect in the truss rod itself or the wood?

Thanks for answer! That’s where I thiiink I can do this, I’ve got enough analog guitar experience and professional software background, I should be able to do it, getting started with the right stuff is always the biggest hurdle.

Step one is filters, gain, and transfer functions with oversampling, adjustable knees, adjustable clipping thresholds, and other harmonic generating processes. That, plus measurements and RnD, can get you a pretty good distortion pedal models.

Then, add threshold controlled dynamics of the clipping properties of the transfer functions and you can begin to mimic the dynamic responses of tube stages when the power supply is being put under duress. Also, add a dynamically controlled DC offset at certain places. Now the distortion devices can start to get amp-like.

I'd love to see what you can come up with. It's a lot of fun getting to make artificial amps in the virtual world.

I don't know the answer but "wavy" isn't a word I'd wanna see in any description of a neck. For just slightly more money you could get a brand new neck from Warmoth with stainless steel frets, and be guaranteed it's not going to have any problems.

Actually I just checked and they have necks on sale, you can get a roasted maple strat neck with a graph tech nut and nickel frets for $199:

All of this is true. Wavy is a very bad thing for a neck to be. On the negative side the other way, Warmoth doesn't offer a painted headstock.

I am curious though if a wavy truss rod would be enough for Fender to second the whole thing. They make enough that they could not bother with replacing it and dump it to the seconded market. Not knowing enough about truss rod/neck interaction is part of my curiosity, I guess.

But yeah, I could always get a warmoth or some other builder and have a custom color headstock done. Reusing what's out there is a more fun

They'll do a headstock veneer if you want. Personally I don't think painted headstocks look right on Fenders, but that's my problem.

Thanks again - Part of trying this out is making virtual amps for my own silliness, and then because I have to live in the acoustic world from 8-5 every day, seeing what I could do in a DSP to improve plugged in acoustic guitar tone. There's some very specific 'off-flavours' that if I can remove in a natural way, would be really satisfying.

having a DSP garnet stinger and herzog will be a blast ha

The recent What Are You Buying back and forth got me wondering -

Have you tried out different direct boxes between the guitar and your software amp sims? Is there a difference?

Not talking about Dr Balls’ tube preamp, but plain jane DI boxes into your amp app or whichever.

Just curious. I’m far too invested in The Past to try for myself, but I’ve noticed DI’s are a selling point on every $3k preamp and was kind of wondering how much they matter for that stuff outside of color boxes and really dry recordings.

That does look cool. I don't give a shit about classic amp simulation, but essentially a fancy sansAmp where you can contour the room sound, cab style, and mic EQ curve is very appealing. Maybe I'll get one eventually to better integrate direct synth layers into mixes.
