Guitar bands - Babyshambles and Kiss? (4)
I believe the answer is:
bass
'guitar' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bass that I've seen before include "deep in the sound" , "Lowest register of the male voice" , "Fish; vocalist" , "Large fish - singer" , "Low singer" .)
