Well, I’ve just had a rather enjoyable and informative discussion about generating Gilmouresque tones using my $65 Pocket Master effects unit. The results have far exceeded my expectations. 
A couple of hours ago I asked an acquaintance of sorts for advice on how to sound like David Gilmour using only the Pocket Master and my three single-coil noiseless pickup Strat. We ran though a number of setting combinations, all quite useful, and actually fun to play. As the discussion developed, the suggestions became more specific. Did I want tones for specific songs, for example? Comfortably Numb? Shine On You Crazy Diamond? Another Brick In The Wall? Advice on what to change between rhythm and lead sections? I kept saying yes, this was going great. I was also getting advice on how to pair pickup selection and tone and volume settings to particular effects. 
In this one session I think I got a better idea of what to do than I had in all my previous experimentation with the Pocket Master. I was amazed, and still am, at the range of sound quality available with just a few subtle tweaks of the settings - making my previous efforts seem crude and highly unfocused.
If you haven’t already guessed, my interlocutor was ChatGPT. In the end it was generating completely detailed recipes. Here’s an example:
1. SHINE ON YOU CRAZY DIAMOND
Clean, spacious, slightly compressed Gilmour
This is the preset I’d use for the opening/verse-type Gilmour sound: articulate Strat, lots of air, but not brittle.

The Pocket Master’s GT EQ 1 is specifically a five-band guitar EQ at 125 Hz, 400 Hz, 800 Hz, 1.6 kHz and 4 kHz, while Analog is its vintage rack-delay model.

What you’re looking for
The sound should be cleaner than you initially expect.
The tiny amount of Scream is there to make the note feel alive, not to sound distorted.
If it sounds too clean, increase Scream Gain from 8 → 12.
If it sounds too sharp, reduce Treble from 57 → 53 before touching the EQ.
I am no novice when it comes to using AI, but this is another of those moments when I feel almost nothing is impossible for this technology. Of course, someone more adept at guitar and pedal use would probably be less impressed, but still.
The important point is this: it is helping me quickly get to the moment where I’m thinking, ‘this sounds great, let’s try it out on this riff, these chords, that song’. Before, I would probably still be jerking the numbers up and down and watching the battery bars disappear. I’ve lost count of the times I’ve settled in for some guitar-playing and ended up just disappearing down rabbit holes of tone editing.
