Mysterman,
Do you mean don't use the sustain pedal at all during some chord changes? I never thought of that. I've heard other pianists do it though. I'll play around with that. The chords do sound heavy, I'll admit.
I'm using a Technics digital piano. I don't have the model number in front of me. It's over 10 years old. So, I'm sure there are better ones out anyway.
