I was just there three days ago!
Cool guitar (not exactly the color for me); BAD directions cop0
If you go South on Harlem, you need to turn RIGHT at 159th St. and go about 1.5 miles or so (you may be thinking of LaGrange Rd/US 45, where you would in fact turn LEFT and go about 3/4 mile).
FWIW, this MGR is the last one left in the Chicago area, and right now it is chock full of CRAP, but dig through most of it and there IS some good crap. Also looks like they may be carrying Schecter, as they have a few new ones hanging up on the "guitars that we deem decent so we have to hang them on the counter-side of the floor" wall
And good to see you here
EDIT- And Ellen, PK's right- that is one HELL of a trip during the rush hour. IMO, that store is not worth the suffering you will endure. I would suggest trying a Saturday morning and maybe making a day of it hitting some other stores as well. Or, like PK says, go to the MGR website or check EBay.
