V for voice, S for Siren sound, and T for music.
AmericaBolt is a patriotic Male FS TBolt 1003, He's got custom omnidirectional ThunderTone horns (yes, FS is said to make a experimental Omnidirectional TTone) Before Siren Tests, AmericaBolt Plays a shortened version of the Star Spangled Banner, before sounding off. He's got a sound that's like trainsandsirens1's B Series 1003 (Chopper level 5). So yeah. He's mainly seen during new years and independence day, but on non american holidays, He's usually chilling (waiting for a tornado).
