First guitarist in heavy metal? (4)
I believe the answer is:
lead
This clue is a quadruple definition!!
'first' is the first definition.
(lead can mean leading or primary)
'guitarist' is the second definition.
(I've seen this before)
'in' acts as a link.
'heavy' is the third definition.
(thesaurus)
'metal?' is the fourth definition.
(I know that lead is a type of metal)
(Other definitions for lead that I've seen before include "first name in lights?" , "Go in front with heavy metal" , "Metal -- Pb" , "Starring role - kind of pencil" , "Be in charge of, element" .)
