Ok, I guess I am going to HAVE to change the speaker in the dsl 401 if I am going to be able to use it at band practice. I did a lot of tweaking and all with it and had it sounding pretty good at home, but I was playing it through a 1960 cab. I took it to practice today and played through it and it sounded like crap. It was OK by itself, but would not cut through the mix. I tried to eq it, but it ended up sounding like it had an aluminum foil speaker. I have never heard any marshall amp sound so sh...crappy my whole life. It was embarrassing it sounded so bad. The other guitar player had a legend 50 combo that sounded like a 1959 sl compared to my amp! So, what speaker do I need? Somebody help me. The Class 5 just blows this amp away and it should not. We are talking paper thin sound. The only time this amp even sounds close to decent with a band is when I play on the clean channel cranked, and even then it still was kinda thin. Marty...speaker-man! I mostly play classic rock. Heavy on 70/80's.
