Welcome - you night want to learn a bit of set-up as you can often get action much lower. I bought a jazz bass once that needed six turns before it became usable - a bus would have fitted under.
Just fitted the cheapo Olympia set 40-100. They seem quite high tension
shocked at how the acoustic sound of the bass has changed. Not amplified it yet
Not sure if such a clause would stand up in real world courts against accepted precedents like fisher v bell and boots v royal pharmaceutical
id argue relative balance of power of the parties against it
You open a case for breach of contract at the local Court. You’ve paid, a contract is made. If they’d just promised, or if you hadn’t yet paid it would be different
