The Line 6 Switch Kit replaces the tactile/actuator switches with high quality soft touch switches.
Works on all modeler pedals (AM4, DL4, DM4, FM4, MM4)
DL4 Switch upgrade worked like a charm
installed these on my DL4. I initially thought the pre-wired cables were too short, but they lined right up nicely after putting it together. My DL4 feels so much smoother now.
