Would i have to get a NON standard hard shell case to fit an Explorer ? By standard I mean one that would fit a Strat an SG or a Les Paul etc.

Thanks for the help.
by that definition yes. an Explorer will not fit into a case made for a Les Paul. they're different sized guitars.
Main Gear List:
Jackson RR7
Agile AL-3100 Double Bound
1977 Fender Jazz Bass
Blackstar HT-5
peavey bass amp
EHX Metal Muff
Ibanez Weeping Demon Wah
Danelectro 7-band EQ
You may be able to get it into a strat-sized case, but not a fitted one. I would say fitted though for an Explorer anyway. If it slides around in the case and let's say it gets thrown off the seat of your car in the wreck, because it lacks extra, form fitting, bracing around it, a lot more pressure is put on the corners when they hit the side of the case
