I bought a new Ampeg 8x10 cabinet a little while ago and whenever I hit the E string, which is tuned down to a D, the volume starts off really low for a second and then comes up to full volume. Is this normal and why is it doing this? And for a second question. The amp I am using is the Ampeg B2R. It sounds pretty good and is fairly loud, but I want more. I'm thinking of buying a power amp to add to my rack. I want to bring the 350 watts from the B2R up to at least 500. So, whats a good power amp that will give me around 150-200 more watts and is fairly inexpensive?
