So I have been running a GBE 1200 into a Genz 610XB2 cab, and I liked it quite a bit except for the somewhat weak lowend. I play a Spector Euro 5 and a Warwick Thumb BO5 through it, and have never gotten the bloom that I would have liked out of lower end. Not long ago, I picked up a Ampeg SVP-PRO preamp, looking for different flavors. Through headphones, the pre amp sounded great, and was giving my basses the sound I thought they were missing. So at practice the other night I ran the SVP through the GBE power section and into the cab. Well, it wasnt what I was expecting. The bloomy lows, ie 60-80 hz, were still lacking. This made me begin to wonder if my cab isnt a little more midrange inherent than I thought it would be. So now, I may be on a cab quest again. I love the 6x10 layout, and I typically prefer 10" speakers. Any considerations? Not too interested in a Fearful setup just yet, and I will definitely be looking to buy used.
