These models feature stereo FX loops and modern component layouts. Their specific Circuit Diagrams can be found in newer service manuals. Official Schematic Libraries

: This is the "secret sauce" in the schematic. Rather than mixing a dry and wet signal into a single speaker, the circuit sends the dry signal to one speaker and the pitch-modulated signal to the other. Your ears "mix" the signals in the air, creating the signature stereo depth. Roland - Global Schematic Variations & Evolution jc-120 schematic

: Early models utilized discrete transistors for gain stages, while later revisions (like the 1984 "H" head model) transitioned to op-amp-based designs. Dimensional Space Chorus These models feature stereo FX loops and modern

has spent over 40 years as the "King of Clean". While tube amps defined the grit of rock and roll, the JC-120’s solid-state schematic rewrote the rules by offering a crystal-clear, reliable alternative. Roland - Global Rather than mixing a dry and wet signal
