This has probably been done many times but I haven't seen it. Please direct me to an existing thread if there is one. Which amp would you have if you could only have one? There are many, many that would work for me, but if I could only have one, it would be my Fender 57 Twin RI. It's the one I have settled on after 50 years of playing and gigging. It can produce enough stage volume for anywhere I play. Most importantly, it produces a feel and a voice that works for me. It's warm and articulate with rich bass, a sweet top end and complex mids. It's touch sensitive. Clean or distorted, it is a beautiful voice to my ear. I can always attenuate it for smaller clubs and mic it for bigger ones. Looking forward to hearing which amp would be your "desert island" amp.
