The STADIUM 80 runs JJ EL34 output tubes in a special dual screen bias mode with three 12AX7’s in the pre-amp stage. All internal switching is True Bypass relays rather than Optical switching that is not True Bypass and slower to engage.
The STADIUM 80 has a dual foot switch selectable masters, master one is cleaner , with the red master being tighter in bass with more available output stage drive.
The left hand volume is your guitar signal pre-amp input gain fixed in both masters. The Blue Gain foot switch will add extra gain pre set by the Blue gain knob second from the left. Think of the Blue Gain as a true tube pedal that is added to your sound.
The Blue Gain stage will add compression as it is increased. To get less compression and more bite increase gain with the left hand volume and run less Blue Gain drive.
The STADIUM 80 has a parallel external speaker extension socket and an ohms selector switch. When running two speaker cabinets, HALVE the total ohms to select the correct speaker ohms switching.
The 0db Line out socket is taken from the output power amp to give a true tube tone not just pre-amp signal.
