The TS10 circuit had some minor variations to the TS9 and TS808 circuits, and is now highly sort after for its secret-sauce flavour.
This circuit includes the true TS10 stock tone in STD mode, as well as two other variation modes:
STD - Classic tubescreamer symmetrical clipping, with the traditional mids focus.
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 - Asymmetrical clipping, with a fuller 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.
