SOLID STATE AMP IMPEDANCE QUESTION

Add some protection diodes on the input in case he does it again.

As it's a valve amp (presumably?) there's not much it could damage anyway - unless of course it's only a 'pretend' valve amp and is mostly solid-state with a few valves. But even then, it shouldn't be too catastrophic.
 
Yeah, I don't like the shrieking of the cellos being destroyed and I don't like the hillbillies singing their Country music.
What was nice is that both songs had no fuzz and no overdriven electronics.
 
AC/DC never played with sinewaves, instead their fuzz and overdrive produced squarewaves.

Which is the entire point, and a great band!.

back when I was broke, the only bands that sounded good through my $69.00 car stereo were the bands that played with as much distortion as my $69.00 car stereo. I'll put AC/DC in the "were a good band based on my current taste" category. Kind of like, "Pabst Blue Ribbon Beer was a good beer based on my current taste (and financial situation) in the 1970s". Since then, I've realized i can afford to enjoy myself so I don't drink PBR and I don't listen to AC/DC.
 
A bowed instrument plays a waveform something like a sawtooth with all harmonics that reduce in amplitude at higher frequencies, and a flute plays something like a sinewave.
I think the only instruments that play a fuzzy overdriven waveform are an electric guitar and an electromagnet buzzer.
An acoustic guitar sounds good.
 
A saxophone (Reed) must look pretty square.

A conventional electric guitar pickup produces "clean" audio waveforms.

The same pickups are sometimes used in electro-acoustic guitars & piezo pickups as more often used in electro-acoustic guitars are sometimes used in electric guitars.

Any overdrive is an external processing effect, which can be equally used with electric guitars or electro-acoustics (or any acoustic guitar with an add-on pickup).

There is no fundamental difference in the audio signal produced from either type - it's mostly conventions and playing styles that divide the two.

Examples - go to about 0:50 in this one:

And the beginning of this one:

In the first video, when the acoustic guitar is playing without the later horrible distortion, I hear a lot of hiss (fuzz?) added to each pluck.
