Ampeg SVX recreates the sounds, operation and feel of the world's most influential line of bass amplifiers and brings it to your desktop. You'll get the legendary sounds of the SVT-CL, the B-15, the 4Pro and BA500, all in a convenient, lightweight and easy-to-use package. When you think Ampeg, you think huge stadium bass tone, but you also think James Jamerson and that fabulous "round" bass sound only a B-15 Flip Top can provide, the sounds that define great bass tone. Take 175lb. of earth-shaking, back-breaking, roadie-killing bass gear and compress it into a mere 3-pound delicate instrument that can equally produce such raw power and emotion and you've got the Ampeg SVX suite of Bass Amps and Bass effects. With the SVX package, you get the Ampeg "Greatest Hits" amps: the earth-shattering sound of Rock & Roll bass of the SVT, the smooth groove making rolls of the B-15, and the scooped edginess of the 4Pro. All Tube, all legendary, all Ampeg.
