I've done many mods to TS's since I bought my first in 1980. Flat freq mods, clipping diode mods, TS-9 to 808 mods, etc. Only two are worth it for me.

Change that turd of an op amp, that JRC4558 to a bi-fet, like a TL072 or LF353. This adds some complexity and the pedal cleans up better when turning the guitar down. The "mythical" JRC4558 was used because it was cheap, plentiful and got the job done, not for any sonic superiority. They were everywhere, like in cheap radios, cheap stereos, etc.

I like to change the drive pot from 500k to 1meg (audio). This increases the amount of distortion available, but the original tones are still there.

I like the stock diodes more than any others I've tried. I don't like assymetrical diode clipping mods.
