I've got an Ampeg amp that is a bit much having to drag it up and downstairs every time I felt like playing with a bass, so I bought a Laney LX10B that I'm disappointed in as far as small practice-type amps go. I'm guessing it's mainly due to the small speaker size. I'm planning to trade it for either a Fender Rumble 15, a Peavey MAX 158 II, or Fender Rumble 25. Are experiences on buying one over the other?
