Just got a new rig for small gigs. An ampeg B2r with a 2X12 combo, been waiting for a month for this, and it IS worth the wait. Great lows, smooth highs and nice middle. But I am wanting to add something to it. I am thinking about getting a little more tone and bottom thickness for the wattage I have in the rig (350). I am thinking about the Aphex, or a tube pre, like the Aguilar... Any suggestions?
