Burnout -> High Speed GTO (can't you hear the tire squeal?)
My friend's nephew is the guitarist for White Wizzard. Saw them with my friend when they came out this way. I end up talking with the guitarist about modded Marshalls while my friend had a headache due to the excessive volume (even though he wore ear protection upon my insistence - lol!).
Ok, hopefully this doesn't sound too weird, but SOMEWHERE in all of this is a positive, it just may take a bit of looking to find it.
I just had this idea: Call up your local newspaper(s). Maybe they can make a story that people will see which might catch the thieves or, possibly, catch the attention of someone who can help. It's worth a shot!
I think in this day and age the best approach is to take a video of everything (showing models and serial numbers), then upload it to the cloud (Google Drive, Evernote and Dropbox all have free tiers, as do others, so there's no excuse not to!).
If you paid originally with a credit card (or bought from a music store), there's a chance they could get you at least some proof that you bought the equipment that was stolen.
I'd get the word out to the local music stores too. Someone might overhear something. Musicians may not agree on lots of things, but they will team up against a gear thief!
