I've been using the Electro Harmonix "double muff" which although being a fuzz rather than overdrive/distortion does give some pretty growly, David Lindley kinda vibes.
EH also do a big muff, a little big buff and bass big muff which I've not tried with Lapsteel but sure sound decent with guitar.
Alternatively there are a ton of boutique companies that offer some great overdrive/distortion/fuzz pedals (check out Zvex "fuzz factory" & "wooly mammoth", Dr. Scientist "elements", Death By Audio "supersonic fuzz gun" & "fuzz war".
Hope this helps! : )
