Mojo, I've got the "bypass" version of the amp. What does that tell me? \:\)

pmbuko... not sure, I would actually define this thump as the opposite of bloated, i.e. it's a tight snappy bass that I'm missing, not the low rumbling tones.

It could be what Randy said that it's too high for the EP600... though from running the test tones and comparing to the bass I'm referencing, I think it's a 60hz sound or just above.
