HP 54600a. It's a fully digital one. On a similar model, you can play Tetris, but not on this particular one. Otherwise an ok scope. But I don't own it, I'm afraid. I used it at a school lab.

Nope. The noise in a DMG is created inside the semiconductor. A prosound mod is about as good as it gets. In your guitar, the pickups are likely completely passive so they are susceptible to picking up external noise, so the shielding makes more of a difference. Also, the shielding in the Gameboy is more likely to be for keeping things in than keeping them out.

And some trivia, there's actually some copper shielding in a DMG, on the back of the CPU board, soldered to it in 6 points.

To comment on what was said above. You can theoretically skip the optocoupler, yes, but preferably not using pins 4 and 5. Pins 4 and 5 are connected to +5V and the signal, respectively. You would have to ideally connect pin 2 to ground, and pin 5 to the input. With this way you probably need to add a pull-up resistor to guarantee that it would work with all MIDI sources. But doing this risks introducing hum since you now have a ground loop. This is what the MIDI standard originally set out to eliminate.

This doesn't make sense. The black marking should indicate the cathode on a 1n914, just like on a 1n4148. And there's no reason you should not reverse the diode either. It should always be pointing the opposite direction to the diode in the optocoupler, or it will mute the signal.

I would much rather than you put the heart on one of the heart code points instead of on the euro sign code point, such as U+2665, and put an actual euro sign on U+20AC, accessibility be damned.

Yeah, but adding a switch is also a risk. The switch may break during a gig or make the GB more crash-prone.
