Ceriatone Overtone SSS 100 preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The SSS JM 100 is Ceriatone's 100-watt amp modelled on the Dumble Steel String Singer, a clean platform with a lot of headroom. A FET input stage with its own level feeds a volume with three-way bright, treble, middle and bass, a rotary voicing-cap selector and Deep, Rock/Jazz and Mid-Boost switches, then tube reverb with send and return, master and presence. Four ECC83s and a 12AT7 drive four 6L6GCs, plus pentode/triode and LNFB switches.
