Dirtbag Deluxe - Reduce Modulation?

[pk1802]

I've searched around the forum, and I didn't find any info on this, but if it's out there, I'm sorry.

I've just recently built up a Dirtbag and the modulation settings are only useful to me in the first quarter of the modulation pot rotation, the rest of the pot rotation is much too seasick for me. Any suggestions? Should I switch the Mod pot out for a 100kA?
