IF this is actually following 1176 use, I'm guessing the input level is totally up to you to control pre pedal. But the sample didn't really feel like a 1176 to me at all. Maybe he limited the actual attack and release times to only a portion of the original because I never really heard it "pump" nor slow to recover. Of course, Brian's sudo-chicken pickin doesn't really lend itself to that either. Would be interested to hear it on bass with some sustain. Without the constant knob sweeps.
