1. When I use a fairly distorted/gainy present on my RP355, the volume pedal taper is rather abrupt, meaning, I cannot go from absolute silence into sound without an initial abrupt (though slight) volume jump. Perhaps this is the noise threshold gate opening. But it's very frustrating. Any suggestions? 2. I notice when I listen to a "clean" or "cleanish" amp setting (no distortion pedal activated) I hear a soft fuzziness shadowing/behing the clean guitar signal. It sounds almost like leakage, even though I know that's not what it is. Any suggestions? Thanks.
