FAB Metal Zone pedal

[CONVOLT]

Hey there! I need some of your advice. Hmm, my Metal Zone pedal is spoilt i think. There's still sound but it sounds very ugly.. I want to repair it but i don't know where to bring it for repair?

sounds 'ugly'... you think the battery needs replacement?

just checking: is your pedal the FAB Metal or Metal Zone?
