Hi folks,

Instead of writing boring paragraphs I'm going to keep this simple:

-When I play bass through the Pod X3 it often sounds terrible and flabby and I don't even hear the correct note;

-I'm suspicious of my headphones, Grado SR60@32 Ohms;

-Line 6 appears to recommend headphones @150-600 Ohms;

My questions:

-What are the symptoms of using the wrong headphones (is it what I've briefly described above)?

-If I buy something like Beyerdynamic  DT-990 Pro headphones @250 Ohms will it help?

-What is the headphone output impedance on the X3?

-Why is finding information about recommended headphone impedance and the output impedance so difficult?

Thanks!

Fred
