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?
That will be for an inspection to look for dope and antiquities and little girls. You would have already paid Greek VAT on anything you bought in the EU.
Depending on how long you have been away I would think there would be less duty and VAT involved in importing your personal stuff into the UK.
It used to be 2 years for a car into NZ at cost.
A few years ago some poor sod listed his sports sedan at a dollar reserve but somehow added the ''buy now'' option. 5 minutes later some asswipe bought it for a dollar and TradeMe enforced the deal.
I think the only way to ship heavy amps these days is with a shipper that does the packing ( and charges the big bucks ) so they are able to insure it properly. Probably they take proper care!
Anyone else, no matter how well you pack it they find a bigger truck to drop it out the back and shrug when it shows up broken.
