"I have been using Fender amps. When I first got here, I was using a late ’60s silverface Champ. We used that for at least half the record. If you want a really big sound in the studio, use a really small amplifier."

"When we were playing somewhere in Mississippi, a sound engineer saw me using the Champ and told me about the Musicmaster Bass amp, which is also fairly small. It has 6V6 tubes and a 12" speaker. It’s 12 watts, with just volume and tone. They were meant to be practice amps for bass players. "

In this video from Fender, Laur Joamet comments on the '57 Custom Deluxe amplifier at 0:16 saying:

Pure rock and roll. It's mean, it's gnarly, and it had got attitude and it's what I want to play when I'm playing one of these. It's a good recording amp and it's really good in a live setting as well. I would even go so far as to say this is more usable and consistent than the old ones, you know.
