Sweet rig man. The rack wahs are awesome. I use a DCR-2SR with my Mark IV and I love it. Definitely the most versatile wah anyone could own I would imagine. I love using the 6th range when playing "Home" from DT. You can really get that huge vocal wah sound. You said you were messing with the eq a bit....a good trick to get a really fat wah sound is use one of the lower ranges (5 or 6) and boost the highs and cut back on the lows with the eq. That'll really fatten up your sound. Enjoy, and post some clips if you could. :twisted:
