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:

• STD - Classic TS symmetrical clipping, with a focus on mids.
• ASYM - Asymmetrical clipping shape begins to ‘look’ more like valve amplifier clipping. This can better suit input signals which already have a full bottom-end, such as a neck pickup, and allows chord detail to better shine through.
• FAT - Also asymmetrical clipping, but with a full bottom-end.

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.
