So, my guitar quit working about 2 weeks ago and the person im buying my next guitar from hasnt fixed it yet.

I've got a concert tonight and my friends brother has offered to let me use his Epiphone LP-100 (http://www.musiciansfriend.com/product/Epiphone-LP100-Electric-Guitar?sku=518661) or the guy from the other band said i could use his Ibanez GSA60 (http://www.musiciansfriend.com/product/Ibanez-GSA60-Electric-Guitar?sku=519536)

There really isnt one specific genre i play. Anything from clean acoustic to metal.

What do you think?
