Cripes, there are a couple of positive responses but overwhelmingly negative.

No. It was crap music, I don't think we ever got past Clare de la flippin' Lune on the recorder, banging random percussion, awful violin lessons and a choir where I was told I couldn't sing so fosters off. Beat all the joy out of music out of me by 11/12 then luckily I discovered real music.

I can see your face in it 🙂

I'm sure they were p-laying Starless in Morrisons the other day - unless someone has sampled it heavily for a pop song...

But whose tongue... and whose cheek?

I can't take them seriously since I found out it was 'bev-iss' and nothing to do with Beavis and Butthead.

There are long and SS versions

Ah drums. The instrument with social distancing built in...

The clue to the bass is those brass 'coins' that anchor the strings, I just wish I could place them...

That's why you shouldn't mark the fret positions 🙂

I think it's a bunch of people all with different expectations and none of them have any will to step back and try and come up with a compromise.

True

The big difference is that professional kit uses frequencies guaranteed to be clear of interference that you have to book and if you don't, you mustn't be surprised if Ofcom of the local authority come and confiscate it because you are interfering with a pro concert nearby. Of course you are only going to go the true pro route if your living depends on it. That said, even the cheap Aamoon scans sixchannels for interference and chooses the best so interfernce is unlikely (unless someone decides to fly an RC drone around the stadium for example...)

Fairy dust.

I made a hifi amp using two as a teenager in the 70s. It impressed my peers 🙂 Filled with nostalgia I have many of the bits (including the power transformer - an RS kit - I wound the secondary by hand!) and have accumulated some more and will be making a new version at some point in the future

Interesting looking here: https://www.gov.uk/guidance/working-safely-during-coronavirus-covid-19/performing-arts#arts-4-7 It says:

It's not digital... there is an ultrasonic bias signal mixed with the audio signal that makes all the magnetic domains jiggle about. During silence, all the domains average to zero. At other times the audio affects the net alignment of domains so the final signal is proportional to the audio (ignoring frequency dependent effects that are processed out). This means the signal can be read back with no more than a simple coil that creates an electrical signal as the magnetic field changes.

I wasn't going to go there as of recently I've learned that it's a rather nuanced effect so careful design is needed for it to work (as your comments imply).

True... I had in mind the venerable and almost indestructible TDA2030 which I see has "short circuit protection, thermal shutdown and SOAR protection".
