I definately can relate to this feeling too. Sometimes when the gig is over I wish we could keep playing. My bass is just sooo good!
My 72 Alembic, serial #16 is like that. Strung with flats, medium low height. Incredible bass. I too have the GK1001, but use either a Bag End 2X10 - the deep one. Or, a GK4x10 sealed cabinet. I like them both for different reasons. The sealed versus rear ported just puts a different smile on my face.
I was wondering about those Eminance Kappa speakers, I would love to switch out the 10's in my 4X10. Going to what's in there now to a 7 ounce magnet would certainly make a change! I am just waiting to hear more about their 10's
I too had one of those Mesa cabs with the EVM. Great sounding cab. I can't even imagine an improvement in sound! That's great if it made such a difference.
Anyone switched to the 10 inch neo's chime in!
