Is there much difference in tone between Epiphone Thunderbird and Explorer models?

I've got an Epiphone Thunderbird and am considering getting an Epiphone Goth Explorer.
But I would be more tempted if there is marked difference in tone (as it doesn't make that much sense to have two pointy basses that sound pretty much the same). Although I have to say I do like pointy basses (unlike most of the folks on this forum).
I also have a Katana and Ibanez Destroyer.
I have to admit they are not that ergonomic, you can't play them while seated. But they look so damn cool.
But to get to the "point" (sorry bout the pun) how does the EPI Thunderbird and Explorer compare?

 

Apparently they "did" make one once upon a time.
Here's the pics.
