This just went unsold on eBay and has been re-listed. Seems like a really good price, though the finish is questionable. I was tempted to grab it myself, but I'd end up routing it for T-Bird pups.

There's an Alpine white Epi that I have my eye on...
The ranking of Gibson related Explorers is as follows (best to worst):
1. Gibson modern day long scale "reissue" ,
2. Epi regular long scale model,
3. 80ies Shadow Explorer,
4. 80ies regular Grabber pups Explorer.
The jump from 4 to 3 is quite considerable - in my ears the Shadow sounds a lot more assertive, livelier and with a voice of its own than the regular model. Fears of it sounding clinical or tinny are unfounded, the piezo works well with the maho body and the sound is actually warm and blurry.
