I saw a friend of mine recently with a healthy amp collection. As well as the Bandmaster with the 3-15 Kustom padded cabinet, we tried some more things out: Blues Jr - boxy. Hooked it up to a 2x12 cabinet - still boxy! Must be the circuit. Champion 600. Not a bad little amp! Speaker breaks up too soon. We hooked it to the 2x12, and wow! That is a great combo. ...aaaand the 5E3. Now I see what all the fuss is about. I almost - almost! - did the Sweetwater "build your own amp" class where you spend two days building a 5E3 clone with assistance. If it were not my daughter's birthday and Mother's day weekend, I probably would have. Now I regret not being able to go. I usually look at amps, and think "it need a mids knob, it needs this, it needs that, it..." Now I get it - less BS, better sound. It just took me a while to get to this point. I am seriously considering a Mojotone or TubeTone or Weber kit now.
