I have this explorer case which is no longer. It has been a great tool over the last 2 years when lugging around my amp to gigs.
An idea of what you fit, I used to carry my Aguilar ToneHammer 500 iside its case, Sl112 cab (with cover), some extra cables and a mini-toolkit. So a lot of space!
I bought it brand new from Amazon 2 years ago and it's still inn very good shape. Handy with its wheels and foldable hands

I'll upload some photos this evening,
Any questions, please ask,
Manny
