Distortion boxes are essentially compressors (in addition to drastically changing the tone color) and so are going to boost any noise present in the input. It may help to reduce the signal level going into the distortion, though of course this gets you less distortion as well. A limiter would also amplify the noise relative to the signal level. The off-the-shelf solution is a noise gate (pedal/effects box). Try it between the TB-303 and the distortion, or after the distortion. Either way should help, but one may be better than the other.

In my experience, Roland=E2=80=99s of this er= a used JRC4558=E2=80=99s extensively, and they are prone to bleeding digita= l noise into the final amp stage. This is most notable with high gains, or = compressors following it.
