I'd play the Jack White just to see what different tones that setup is capable of, keep the Vernon Reid just because it's the most usable set up for me long term, and the finish the chipping on the McCready (someone has clearly already started that process).
I'd keep the Jack White guitar. I don't have a bigsby but have enjoyed using them on guitars I've played. I like the weird pickup config too, and maybe could learn to deal with one of the ugliest body shapes electric gutiars are made in. I've played plenty of strats, so would probably chip that - leaving the Vernon Reid to play.
I'd play the 7 - looks like a beaut and looks easy to play
Keep the Martyr II Custom - love reverse headstocks and vibrato, that's my jam
Chip the Martyr - not useful to me between the 3
Keep the 7, always room for another of those - flat black, simple, graceful, nice control placement, no complaints
Play the Martyr II... love that top wood, really the whole thing is a nice vibe even if not completely "me"
Chip the red Martyr with little regret, that color and those inlays, tacky as hell
I'd keep the Angus SG. Wood chipper for either LP. Sell the other LP to buy Carlos Woodstock SG...or Tony Iommis SG special or Duanes 3 pickup SG
I tend to look at LPs as amazing sounding guitars that make my back hurt and have zero high fret access.
I had one LP for 6mo, sounded great but felt like i was playing a cinder block...not a hollow one either
Then again I'm partial to SGs......
play the dime, chip the art deco esquire, keep the other thing i guess. those are all chip worthy. and for that price you could almost get one of those new prs things with the fleshlight built in
