From an interview with Anders Osborne:
"I like mixing big and small amps. I used a 100-watt Marshall JCM800, a 64 Fender Concert, a 50-watt Marshall plexi, a Vox AC30, a 50s Silvertone 1x10 combo, and a vintage Gibson 1x8 combo. A custom splitter box sent the signal out to four amps, and I daisychained the others. Certain combinations such as the Concert and the JCM800 sound awesome chained together. I plug into one input on the Concert and then run a cable from its other input to the input of the JCM800. I lined everything up in a big room and shuffled the order until I found my sounds. Then I moved around the room to find the sweet spots."
