OK! I'm still in the middle of my quest for a new practice amp, lightweight, with around 100W of power. I bought an SWR Workingman's 10 a few months ago. Nicely built amp, but I just couldn't get into the sound. So, I sold it. Broke even. Now, regarding the Carvin PB-100. Here we have a 100W, 35 lb amp, or reasonably small dimensions. But! How does it sound? What about the quality? Anyone have any experience with one of these? I'm looking mainly for its application with a P-Bass. I don't expect a single 10" speaker to give a whole lot of response to the low end of a 5-string. Thanks!
