The TS10 circuit had some minor variations to the TS9 and TS808 circuits, and is sort after for its secret-sauce flavour.
The classic TS10 stock tone is achievable in STD mode, as well as two other variation modes:
The gain control has twice the amount of gain range as a classic TS. The extended range begins at the 2 o'clock position onwards.
The chip has been upgraded to a higher performance audio amplifier by JRC (Japanese Radio Company). The clipping is shaped by driving the three specially selected black glass tube silicon diodes.
