There's a far eastern possibly Buddhist lesson that goes something like
A scorpion is on a journey and comes to a river. There's a cow on the river bank so the scorpion sidles up and begs a ride across. The cow is a bit reluctant but agrees and transports the scorpion across. The scorpion stings the cow a lethal sting as he hops off. The cow plaintively enquires 'what the duck?'. Scorpion shrugs 'I am a scorpion, that's what we do'.
I would be resigned to the fact that it's all out of my hands and the dealer's hands until the wheels grind on at USPS.
I hope it is fully insured so the dealer isn't out of pocket when ordering up the replacement. If you ordered from the dealer he's on the hook to provide or refund you I reckon.
When I lived in the UK I had yet to set foot in Australia. ''Wot, you never been to Australia!??" ''Yeah, ever been to Russia?''. Same distance, not like popping over to Paris for lunch.
It's a very flimsy film so you wouldn't want it anyway. I once bought a near new Jazz that the original owner hadn't removed it. At first I was horrified that he had replaced the original scratchplate with a graphic guide loaded one! Off it came. Iirc the only thing holding it down was ''static suction'', or at least no adhesive to see.
My set lists have Extras at the bottom. Sometimes we play some, or all of them, depending on what happens. If we have taken a bow it's not often we will play more after that.
As an alternative to potential trip hazard or nipple ring tearing out I suggest the following amendment.
Get in the habit of saying ''I am putting down the bass, I don't want to Downunder my nipple, I mean run down my battery'' and unplug.
It has one end with the XLR 'mic' end wired up unbalanced and the other is standard TS 1/4". Agedhorse will fill you in or you can look up the Rane note for unbalanced XLR.
The reason for the simple lead insertion = on system is it is the most reliable for the most people. A separate switch is prone to be forgotten and the bass put away in the case to be found dead on next use. Those are the choices until you go for complicated electronics which would increase the cost.
Tough luck Buttercup!
Of the potential practical solutions I like the reminder loop of string around your leg from the lead plug.
The first time you forget to toggle off your custom foot switch TRS lead combo you'll know I am right.
Noodle with another bass?
Get in the habit of unplugging it to put it down?
Rewire the preamp power supply to a new switch?
I think if you are going to forget to unplug you are going to forget to toggle off a foot switch.
Velcro your good self to the lead when you plug it in so you can't forget?
