I have been using a Boss Katana 100 watt amp with a foot switch on and off for the last five years depending on what type of music I'm playing. The sound is adequate. Can't be compared to my Carr Rambler or other tube amps I own. The pluses are they are light weight, inexpensive, and I don't care what happens to it. It's a little banged up but still works fine. If and when it stops working, I will throw it out, save the Boss footswitch and buy another one.
