I am lucky to have some friends who are engaged in the music industry. I have a former colleague who now owns his own live band. I am very proud of him. During our last conversation, he asked me to search for the best rivera amp. I am not really the right person to ask for things about musical instruments. He requested me if I can find cheap ones here in the US. He then told me the company of the amplifier he needed and I am glad, he finally bought a new one.
