Does anyone know if there are black firebird copies out there. I have been wanting one for ages after seeing Dave Grohl playing his. Since I am only 15 i do not have enough money to get a Gibson firebird, so any substitutes?

That would seem to be your best choice as copy companies like ESP usually just copy the explorer.
I don't give a shit if you listen to me or not
Thomman have a Limited Edition black Firebird (Epiphone) you could check that out. You could also buy a black pickguard somewhere if you want the full black look.
