The 410 utilized 10" Fender Special Design speakers made by Eminence and was available for versions II and III.
[1][2] Fender described version III as incorporating modifications to the preamp to provide the drive channels with "more modern distortion," switching to Celestion speakers for the 212, and changing the control panel from chrome to black, for better visibility on stage.
Other features include a Bass, Middle, and Treble EQ, Master Volume, Presence, Normal/Bright switch, standby switch, preamp out and return for an effects loop configuration, and a Fender long-spring reverb (solid state for both the driver and the recovery circuits).
Its circuitry includes full PCB with valves and pots mounted directly to the circuit board.
