Ok, so recently I've been hauling around my ampeg BA115 HP a lot and have come to the conclusion that it might be worth it to upgrade to a better combo. I've been tooling around on this http://bass-guitars.musiciansfriend...0500W-2x10-TiltBack-Bass-Combo-Amp?sku=481794 for a while now and have come to love it. However, I have heard many good things about Genz Benz and was possibly thinking about purchasing this combo http://bass-guitars.musiciansfriend...0-Watt-Lightweight-Bass-2x10-Combo?sku=482112. Between these two combos what advantages would the Genz have over the Markbass? Also, are Genz-Benz products US made or asian made?
