Continued from the page on AC30s with . Also encompassed below, Super Twins with numbers in the main AC30 sequence - Super Twins (and Super Twin Reverbs) by this point had a sequence of their own beginning at .

Throughout the 13000s, as in the case of amps with numbers in the 12000s, one finds three models: the "Treble", designated with a "T" on its serial number plate; "Normal" voicing designated by an "N", and Bass designated "B".
