Using the Fender Bassman 100 presently. Excellent sound. This may sound daft to the majority of bassists - but the weight is an issue for me. Phil Jones Brief Case is much the same weight, but would appear an easier lift due to its shape & centre of gravity. I know the Genz Benz 3.0-10T is way lighter & wonder if the 6.0-12T is worth the extra weight. Has anyone compared these exact amps with the Fender Bassman 100 ? Would it be a step up, or a step sideways ? I'm a clean deep sounding old school bass player, using mostly an American Fender Jazz Passive & Boss GT6B. Do lots of church work, but also gig with a wedding band at times.
