Thanks Ed. The I40 appearance is what I was shooting for. I keep flats on my Hofner and my Gibson EB-3. So, that particular P-Bass is actually wearing some nicely broken-in Fender roundwounds. Gives me great growl through the Sunn, with nice punch. That bass goes from Jamerson to Entwistle in a single turn of the tone knob. But, it never sounded better than it does through that Sunn. What a great amp.
