5. Hook up headphones and poweradapter, tune TM1 to your liking. (or the right Hz that you find in the tb-303 servicemanual. I do not know this value at the moment.)

6. Do NOT touch TM2!!

7. Put it back together in reversed order 🙂

Enjoy the ”darker” sounding tt-303, we think it makes a huge difference but open it up at your own risk, warranty problably wont apply after these actions.

if you missed it, there is also a video above that shows how tuning the TM1 will affect the overall sound.

    It’s possible to access the TM1 adjuster through the mode selection hole on the front panel when the button is removed:

    Just need some light and a thin screwdriver.

    In your opinion is any way to control the cutoff via midi or via cv-gate-midi as in the tb 303 with kenton kit?
    in other world: does the kenton tb 303 kit compatible with the tt303 bassbott?
    Thank you.
