Gain on your amp obviously helps, but notice that most of it is physical technique. Practice slightly adjusting the amount of contact your thumb makes with the string after picking. I've noticed that a heavier, thicker pick is also better for this because it provides more precise control of when, where & how the pick strikes related to your thumb grazing the string afterward.
Hope this helps. Best of success with it!
