Ok, so I was in a band recently...I used this combination when we would practice. However, I noticed that I couldn't keep up with the other musicians volume-wise and I couldn't get connected into the PA because the manager (and mixer) didn't have the proper equipment to hook me up into it. Anyway, I noticed that if I tried to boost the volume, I would get heavy distortion and not much of a volume increase (cause it's a tube amp...duh). This isn't my issue tho... The manager said that he would have a friend of his look at the amp. When he came back with it, he said that the amp was doing this because it wasn't powerful enough to power the 2X15 cab. This sounds like BS to me, especially since the two pieces were sold TOGETHER in the 60s. Thoughts? Should I get a second opinion?
