It would be wireless from your guitar to the pedal chain. The pedals will still be running off mains. So no help with the buzz but might stop you from getting electrocuted! Personally I would look at an RCD socket adapter instead, to deal with any safety risk. For the hum, hopefully someone more knowledgeable can step in but I believe there are filtered four-ways available to protect IT gear against dodgy mains that might be worth a look.

I feel a bit bad about the amount of self-promotion my friends and family get exposed to via my social media. I'm forever pushing some project via my own social media accounts in a desperate attempt to fill a venue or whatever, and it must get repetitive.

I use an ART Tube preamp with double bass; I have a gig coming up for bass guitar and I'm planning to just take the ART for that, no amp. I'm pretty confident that it will sound ok.

No idea but F and B flat are more common keys for bands with lots of brass, big band type arrangements. You could always sit down with an instrument and go through YouTube or Spotify playing along with all the available versions.

If the desk has a low cut button (<50hz) on each channel, which they often do, you could do worse than just hitting that on every channel. I find that for double bass the real action is up around 100 to 200hz, and you can roll everything below this right back on your own amp (or with a low cut pedal).

A discussion about tuning that rapidly escalates into a fist fight - definitely takes me back to a couple of past studio sessions...

It's also possible that the singer's mic is picking up the bass and sending it through the PA, then the body of the bass resonates with the PA output, that comes out of your amp and back into the singer's mic, and you have a feedback loop. You could ask the sound engineer to roll off the bass on the vocal mic - you could probably wipe off everything below 150hz without it doing much harm for a female vocalist.

You could always buy my Ibanez Axstar, which is different in all kinds of ways but very 80s and also taking up space in my tiny office room.

The fourth dimension is indeed time. It's best left set to the present moment though, I accidentally gave mine a tweak and I'm not going to see it again until next June.

Jean-Luc has it right. Reverb will charge VAT on the fees then send it to HMRC whether you have a VAT number or not. If you had one, you could reclaim that VAT, but the customer's VAT status is immaterial to the supplier. Tell them you're a private seller and not registered for VAT, and to hurry up and pay out or you'll report them to HMRC.

As an aside, if anyone can think of a good name for a bluegrass band playing covers of 80s pop hits, that would be great.

I had a job once in which I had to sit in on loads of job interviews as part of the panel, but I wasn't really the key player in making the decisions - I was there more to ensure consistent and correct process. It was a fascinating experience. What jumped out is that there's always a specific situation going on for the employer that the new person will have to step into, so that the employer always has a strong idea of the kind of person they need, but the interviewee doesn't and can't know any of that. It made me much more relaxed about getting interviewed myself. You can't know what they're after, so you just need to present who you are and what you can do in a clear and friendly way, and if it lines up with what they need then great, and if not then there's nothing you can do about that. We turned down loads of great people because they weren't quite what was needed - no reflection on them at all.
